The market is falling sharply, I see signs of not healing, capitalization is withdrawn, should I continue to buy in the top 10 coin or should I pin down USDT and wait for new move? 
Do not need to buy at a fall in prices. It is better to wait until it is over and the trend changes to a growing one. If you buy during the fall and the downtrend will continue, it will make you nervous and make bad decisions that can lead to some losses
