In my opinion it's the same thing that you are buying fiat or participating in Forex! This stability is misleading because at the cost of this fixed price an inflation and printing of these papers at all time! Tether is basically endless and other stablecoin too! If you are not a trader, it does not make sense to buy or have deals with it.
I do not agree with you. I think that stablecoins are well suited for profit taking and are very important for traders. It is important that steamers pass the audit and are really provided with dollars in a bank account.
