First Stablecoin Trading Pair Goes Live on Binance DEX

Seattle-based venture-capital backed blockchain startup Stably, the issuer of USDSB, the first stablecoin to be launched on Binance Chain, has announced that a trading pair for USDSB is going live on Binance DEX today (June 24).

Seattle-based Stably was co-founded by Kory Hoang (Chief Executive Officer), a former Private Equity Data Analyst for PitchBook, David Zhang (Chief Technology Officer, who used to be a Software Development Engineer at Amazon, Amiya Diwan (Chief Product Officer), also a former Software Development Engineer at Amazon, and Bryan Guy (Chief Legal Officer), who is a licensed attorney.

Stably announced on 1 November 2018 the early access launch of its pegged and fully dollar-collateralized stablecoin, StableUSD (USDS), which had first been launched on the Ethereum mainnet on 16 August 2018. Stably said at the time that the fiat reserves were held in FDIC-insured escrow accounts managed by custodian Prime Trust, and that a leading accounting firm, Cohen & Co., would be conducting weekly attestations for these fiat reserves. 

Then, on 1 February 2019, USDS got listed on Binance’s centralized exchange (, and two trading pairs for it—BNB/USDS and BTC/USDS—went live on 5 February 2018.

Later that month, trading pairs to support trading USDS against four other stablecoins—USDT, USDC, PAX, and TUSD—became available on

On March 18, Stably said that USD had received support from Binance’s over-the-counter (OTC) desk. Kory Hoang, the Stably CEO, had this to say at the time:

“Partnering with Binance OTC allows us to provide even more liquidity to trading shops who want to move large amounts between major cryptocurrencies and USDS.”

In a blog post published on June 3, Stably announced it was going to issue StableUSD on Binance Chain, and that USDSB, a BEP-2 token, would become the first stablecoin on Binance Chain. Mahraan Qadir, Director of Product Management at Stably, went on to say:

Building on Binance Chain provides many benefits for stablecoin users, such as improved security, ease of use, and speed of transaction. This makes USDSB one of the fastest major stablecoins on the market, with one-second block confirmation time and the ability to process several thousands of transactions per second.”

He also said:

Expanding onto Binance Chain will also allow the Stably team to eventually submit a proposal to list USDSB on Binance DEX, an initiative that we are planning to achieve in the coming weeks. If it is approved by the validators and gets listed, USDSB will become the first stablecoin to launch on Binance DEX…”

Well, now, three weeks later, we find out via another blog post by Qadir that USDSB has indeed been listed on Binance DEX and that trading pair BNB/USDSB is going live today on Binance DEX (expected to happen aat 10:00 UTC). Furthermore, he says that Stably is “planning to list USDSB with additional assets on Binance DEX very soon.”

Also, according to Qadir, today, two trading pairs for USDSB are being launched on USDSB/USDT and USDSB/USDS.

This Ethereum Lottery Perfectly Explains How Facebook’s Big Corporate Backers Will Profit from Crypto

To understand how early investors in Facebook’s new Libra blockchain will make money over time, it helps to dig into a new lottery going live on ethereum mainnet Monday.

It’s a lossless lottery called PoolTogether and tickets are now on sale. Its similarity to Libra is not a completely one-to-one relationship, but the key insight of both is the same: Earning interest on your own money is good, but it’s better to also earn interest on other people’s money.

So first let’s explain this new ethereum game before circling back to Libra.

On PoolTogether, each ticket sells for 20 DAI (the stablecoin generated by the MakerDAO protocol, which aims to keep a stable price at $1.00 each). Each pool sells as many tickets as it can, and all the DAI gets put into the ethereum-based money market protocol, Compound. There, all the ticket money collects interest over the life at the pool and at the end, one ticket earns all the interest off everyone’s ticket price.

But everyone else gets the money they paid for their tickets back, too – ergo, no losers.

Gamified savings

“What excites me is that I think it can actually move the needle on economic health for a lot of people,” PoolTogether’s creator, Leighton Cusack, told CoinDesk.

People get excited about lotteries. They don’t excited about savings accounts. This is a way of nudging them in the right direction.

The idea of putting the concept on ethereum was first discussed in a popular post on the MakerDAO subreddit in late March, and the project has been made possible thanks in part to a $25,000 grant from MakerDAO, the company.

“We think it’s good for the ecosystem,” MakerDAO’s Richard Brown, who runs community development for the decentralized finance firm, said of the project. “One of the things that interested me the most about this is it has the capacity to take a behavior that was essentially a tax on the poor and it allows it to become a tool for social good.”

In other words, lots of low-income people gamble despite dismal chances of ever benefiting. Personal finance site Bankrate has found that people are less likely to buy lottery tickets as household income increases. PoolTogether takes the attractiveness of gaming and combines it with the healthy behavior of delayed gratification.

The strategy isn’t without precedent. Walmart has actually been running a gaming mechanic to encourage people to save money on their cash cards. People have locked up over $2 billion since 2017.

With no risk of losing money, people start saving money rather than spending everything they have. With the returns on a typical savings account currently at 0.9 percent, it’s not even irrational for a new saver to participate in a program like this. The opportunity cost is quite low.

PoolTogether’s approach

At first, there will only be one pool on the site. It will be open for tickets for three days and then the winner will be announced after earning 15 days worth of interest, on July 11. PoolTogether will shave off 10 percent of the interest earned for its business model and the rest goes to the winner. It’s all defined in a smart contract recently audited by Quantstamp.

MakerDAO’s Brown believes the model could become a frictionless way for large groups of people with disposable funds to support good causes.

For example, someone could create a decentralized autonomous organization where all the interest on a pool goes to a wallet controlled by a non-profit of the winner’s choice (rather than into their personal account). He called it a new kind of “primitive” for decentralized finance, saying:

“It’s pretty low-friction. It’s pretty low-risk. It’s low-stress, because no one is coming out of this thing broke.”

PoolTogether’s Cusack foresees the project starting off just big enough. He wants the first winner to basically double their money off the winning 20 DAI ticket. That’s going to take getting a pool together of 100,000 DAI, Cusack said, which is a big goal but they already have several commitments to prime the pump with 1,000 DAI each.

So what about Libra?

Libra is also designed so that a select few capture the interest earned on money tucked away by the vast many.

As CoinDesk previously reported, there are two tokens that make Libra work. Most of the attention has been on the Libra coin, the stablecoin backed by some as-yet-unnamed basket of bonds and currencies. To get that basket started, though, Facebook came up with the idea for the “Libra investment token” (LIT).

Like PoolTogether, the whole point of LIT is to earn interest off other people’s deposits.

To make sense of why this is so powerful, think of a very simple example. Imagine one LIT sold for $10 million. Invested in a basket of boring, safe investments, Canaccord Genuity has projected the reserve should earn about 0.25 percent. So $25,000 in a year on $10 million. That’s not nothing, but it’s a lousy return for a tech investor.

But imagine 100,000 people decided they wanted to use Libra coin, and all of them bought $100 worth each. Now that holder of the one LIT will earn $50,000 in a year, because the reserve was doubled with other people’s money, but only the LIT earns the interest.

Now, this is a global project, so obviously Libra’s backers want to get in a lot more than 100,000 people. Even if a billion dollars in LIT tokens are sold, with companies like Visa, Uber and PayPal involved, there’s no way they aren’t targeting many, many billions in the reserve. With each additional billion, the returns multiply to LIT holders.

Canaccord Genuity estimates that if Libra coin gets a market cap equal to bitcoin’s, $162 billion, then $324 million could be paid back to all LIT holders each year, after subtracting operational expenses for the Libra Association.

Let’s assume no organization holds more than one LIT and the Libra Association hits its 100 founding partners as planned: that’s a $3.24 million annual return on each partner’s $10 million investment. It’s not a one-time return either. They keep getting it as long as the Libra coin keeps running.

So 10 years after it matches bitcoin’s market cap, a LIT holder would have earned $32.4 million without losing any of their principal, a better than 300 percent gain. And that’s assuming the reserve didn’t grow at all as the decade passed.

On PoolTogether, everybody is betting that they can win the interest off of everyone else’s tickets. A crypto newbie could buy one ticket for 20 DAI and get all the interest earned off a whale who bought 1,000 tickets.

On the Libra protocol, it works the same way, except the same whales always win.

It remains to be seen if Libra will get to that point or if it will even get off the ground, but PoolTogether is starting now for anyone who wants a shot at robbing a whale. The person who created the product that will host the first pools, Compound’s Robert Leshner, told CoinDesk that he’ll definitely be buying some tickets in the first round.

Said Leshner:

“We love watching the world experiment with new products and new ideas built on top of Compound no matter what they do. I’m excited.”

LTC沿三角上边线震荡上行 或将还有冲高的机会

从LTC/BTC 4小时走势能看出,近期币价一直处于下滑趋势并连续阴跌至目前0.0125BTC附近,目前已破位上方关键支撑线0.0127BTC,那么下一强支撑位在0.0111BTC附近,4小时MACD快慢线有缓和趋势,RSI再次进入超卖区间,短期币价有向上回抽前期支撑的需求,再看近期LTC/USD 4小时走势,前期LTC一直处于上升楔形三角区间内一路震荡上行,并在6月10号放量突破三角上边线,这几天币价一直沿三角上边线缓步上行,期间多次回踩并未出现破位,量能再次处于缩量态势,上涨动能不足持续性受限,短期仍将延续弱势震荡走势,中期看在8月初即将产量减半的利好刺激下币价还有上涨的预期,后续LTC沿上边线反复震荡洗盘后,可能还有上冲的机会,短期支撑130美元,阻力145美元,中期160美元。

Will Bitcoin Take a Breather or Blast Through Resistance Again?

This weekend has been nothing short of monumental for Bitcoin. Over the past two days the king of crypto has surged almost 15 percent to its highest price for 15 months. The big question now is will it carry on brushing resistance aside or is a pullback imminent?

Over the past 24 hours Bitcoin reached the giddy heights of $11,250, its highest price since March 2018. Market dominance is close to 60 percent as the altcoins remain frozen over, many still down over 80 percent from their peaks. Daily volume topped out at $30 billion as BTC market capitalization touched $200 billion, but has the wave of FOMO crashed onto the shore?

Bitcoin Breather Beginning?

As in previous pumps, traders and analysts have been scouring the charts looking for resistance zones where Bitcoin may possibly halt its epic run. $10k was a huge psychological barrier that was blown away within a couple of hours when BTC surged to $10,900 on Saturday.

The next key resistance level is around $12k where BTC touched on its way down in early 2018. Trader ‘CryptoFibonacci’ has looked at the long term chart to ascertain if and where Bitcoin may take a breather.

“Price is getting to an area where one would suggest we take a breather. But, BTC has a mind of its own, so we shall see. If you have profits, I would suggest taking some off the table the closer we get to 11,500-11.800 area, IMO.”

Other long term technical indicators are all indicating bullish momentum for Bitcoin so a correction would not be a bad thing. Economist, Alex Krüger, notes that trends are all one way at the moment;

“”The trend is your friend”. Returns and sharpe ratios for $BTC longs taken above the various moving averages are significantly superior than for longs taken below the moving averages. This is particularly relevant for trending assets such as bitcoin.”

The CME futures chart is starting to show some ominous gaps which is an indication that the current bull run could be running out of steam. CryptoFib added;

“They are open now and we have yet another gap. Not surprised based on the weekend move.  But, look how far price is outside of the upper Bollinger Band. That is No go for new longs for me. Time to take a few off the table, IMO.”

Analysts have been wrong in the past when they predicted 30 percent pullbacks at $6k, $8k and again at $10k. Now that Bitcoin has breached $11k the correction calls are getting stronger so it has to take a breather sooner or later.
