At the moment I think that BUSD and USDT are the safest stablecoin pairs for regular cryptocurrency trading but I'm afraid that Binance has so huge influence on the market that if it makes mistake, BUSD may get fucked.
USDT seems to be the safest, am I right? What are the possibilities that USDT may end up like TerraUSD?
Which stablecoin do you suggest for crypto/usd trading?
I also think that the two stablecoins that you have mentioned, USDT and BUSD should be pretty safe. There are huge companies behind them which should have enough resources to back the stablecoins that they are minting. I know that there have been rumors regarding USDT for a few years now that we can not be 100% sure anymore if they are really having enough resources to back every USDT that they are minting because they changed the wording regarding that topic a while ago, but recently i have read that the company behind USDT got audited a few times and that everything was fine.
My personal favorite of all stablecoins is USDC though. Even during the bear market of the last months it was always at 1 $.
