I'm just curious, why do exchange always attempt to create new kind of cryptocurrency that can replace USD?
In my opinion, It's much better if you can just convert it directly to USD, so trader may assure that their money in the trading site is really equal to 1usd.
What is your option on this matter?
So that stable money can only be traded in the same exchange, which means that it can provide earnings from interest. Also you can not make withdraw that stable money from the exchange to other, you have to change it to Bitcoin or another one. So Bitcoin's price is higher when compared with other exchanges. If you are just using an exchange, maybe this might be useful.
