Ever read their fine print! 1 USDT is not a promised USD, no thanks.
Who says you need to hold it for long? Short it while there is profit to be made and you're good to go.
The reality is that if you believe in the fundamentals of bitcoin and crypto, now is a good discount on prices that we are having. Do note that short USD (expecting USD to fall) is also one of the most crowded bank trade at the moment. Any USD related invesment is probably not the wisesest either.
Yep, a basic fundamental and trading practice, except that nobody knows what will be the bottom that's why no one has dared to buy serious amounts yet. People will buy if China's stance on bitcoin has become clearer and whether or not we're ready to trade without them. 'Til then we'll just let the price tank even more until we're certain about something on this crazy market.
