I don't use tether because its a scam so is likely to be investigated which will drop the price

But I do use dia and tusd as stable coins, as well as pax gold

Profits from cryptos go half into gold and half into stable coins ready for a buy back

The gold is not for making gains, it's insurance against losses

Longer term the US dollar is screwed, but stable coins linked to it can work for trading in the short term
