In spite of the words mentioned in the article, I consider that stable are not important to the speculators or me.
stablecoins are companies or individuals that want to buy a token/crypto with the guarantee that you will get $ 1 "or any amount" when you want to sell.
So we came back to the central system with a new concept that individuals or companies can create money "We must trust their promises" that is more dangerous than the current financial system.
Also, some decentralized systems "which I think" it is better but still risky.
 It’s my impression of those currencies.
