I really like stable coins you can make good profits by putting them in stakes and with this crisis for the virus they are an excellent safe haven alternative to cash / fiat
indeed only stable coins can still survive when there is an outbreak of this corona virus, but I am sure stable coins will not be able to provide much profit like bitcoin and other altcoins because the price increase depends on fiat price movements.
Yes stable coin is immune from market fluctuations as its value depends on fiat i.e USD, but I don't think fiat will ever be used for investment purpose as it's just used to store value during uncertain market situations to avoid losing money or while trading stable coin can be used but it can never gain status of other crypto coins.
