The market is falling sharply, I see signs of not healing, capitalization is withdrawn, should I continue to buy in the top 10 coin or should I pin down USDT and wait for new move?

I am really sad when the altcoin fell sharply. I think they will continue to decrease in the future. As the altcoin drops, people like to buy into. But in this reduction, the altcoin is experiencing major problems. I think the altcoin will continue to decrease. Should not buy at this time. Many countries have in turn introduced policies to block altcoin-related transactions.
I think there needs to be faith and for alcoins the chance of recovery, my move will embrace the coin potential and good foundation.
