Im on the newer side to crypto, just want to say that first.
Tether always stays between .99 and 1.01. How, I dont know. With it never really changing in price, why not convert your cryptos to tether to avoid losses when the market is crashing?
I have been implementing that strategy. It was quite effective for me but now the market is volatile, I can not make much profit for myself. I think there are many investors trading that everyday. But the disadvantage of using USDT is that the transaction is very slow. I used to switch from USDT to cash but it took more than 3 hours.
