During this period and days, do not judge a currency by saying that it is good or not good, because the market is volatile and do not fall into the trap of buying a currency. Keep your balance in dollars and when the turmoil stops, try to buy. Now, trade BTC, whether it is a sale or a purchase, with weak demand rates. Add your amount if the order is a purchase, and a basic condition is a limit order. For example, the market price is 60, you buy 85, and the sale is the same.
