stablecoins are really useful in this market that is always volatile, you can keep your assets safe at stablecoins, useful in buying and selling very large because their value is not lost, and traders need stablecoin.
Anyone who sees negativity in stablecoins is not a real trader. The crypto market is highly volatile and wise traders lock profit in stable coins. Some even hold stablecoins to take advantage of the market during massive dips, which is a nice concept. Aside the legal issues faced by Tether (USDT) founders now and then, I don't see any negative concerns for stablecoins.
at the moment I see that the products of the USDT are not too much of a concern just because the legality constraints of the government are not overly thought because so far as I know any digital currency or cryptocurrency that uses blockchain technology, the government will not be able to control it in any way, the movement of the coin depends from the owner himself.
