Yes USDT has management flaws but these are caused by limitations placed on their access to banking services - they have a long history of making sure they can maintain peg in spite of constant attacks from regulatory authorities, short sellers, and negative media publicity.

No, I don’t recommend using USDT. But with the regulated coins being operated much more poorly than USDT, it may be the best option in certain situations.

I would say the flaws are caused by deliberate fraud, and I don't trust their figures or those of crypto exchanges, given they have close relations with several large exchanges.
