During times of crypto blood bath,I prefer to sell off my portfolios and buy USD Tether which usually fluctuates minimally.Any better options or thoughts on this?
Well that's the hole point on buying tether, since it's suppose to act as a a virtual dollar. Of course that since it's not an actual dollar, it can lose value or even be shutdown, since it's centralized. I think that if you can have access to an exchange that actually pairs bitcoin to fiat, you should opt for this instead, as you would be much safer this way. It's still an exchange, and we are seeing some banks temporary closing exchanges accounts, but I would still prefer it to tether. There are also some coins that are outperforming bitcoin right now, so you could also try to accumulate more bitcoin by trading those pairs.
If you want to go on USD temporarily, you might as well use USDT to bypass all the bureaucracy of going back and fort into fiat, this was the original point of USDT.
The problem: The exchange with the best volume for USDT is Poloniex. Poloniex used to me freedom friendly back in the day, nowadays it's another hellhole of verification. I believe you can't no longer use Poloniex without verification, even to trade between alts, just like Bittrex. So you can't no longer use USDT as an anonymous way to go in and out of crypto in a token that's stable. I don't know if there are more exchanges that are anonymous with USDT, but I wouldn't expect good volumes there. USDT also has an inherent risk of blowing up at any second, just like any token pegged to a fiat currency.
