There are many stablecoins out there, and most of them are either not stable or they are stable at a very high price to those maintaining the stability. I haven’t yet seen a crypto-collateralized stablecoin I thought would work. If anyone is going to do it, I have high hopes for the Reserve team, but they have huge regulatory headwinds in front of them.
One smart stablecoin is the ndau, by Cosimo Ventures (disclosure - old friends of mine). ndau is a stablecoin backed by a large basket of mostly real-world assets. It is priced using curved bonding. That makes it very interesting. It’s a significant project with a lot of good thought and people behind it. The product is just now getting listed on exchanges.
