Given the current market conditions, here are some sincere pieces of advice:

In a deep bear market, control the frequency of trades and the urge to use excessive leverage. Minimizing losses is equivalent to making profits. Eliminate all unrealistic expectations. 99% of altcoins have no future; they will never return to their previous highs and there will be no more altcoin boom cycles. You can't make all the money in the world, but you can lose everything very quickly.
