I trade during such a deep correction, if only if there is a fundamental confirmation (positive news, insider) that the price of any altcoin may begin to rise. At the same time, I must adhere to the principles of risk management and diversification.
I dont really do trading when the market is red because i know to myself that i can not earn a big profit if i will still trade even the market is red and for me the best time to trade is when the market is green so all the coins in the market is will be high.
