Learn from my mistakes to learn how not to repeat the same mistakes and always carefully analyze a coin before deciding to trade. Besides that, don’t be too greedy in taking profits even if the condition of the coin’s movement is good because the coin’s movement can change at any time. If you see a decent profit, immediately close the trade and wait for the time to enter the market again. Don’t expect to get big profits every time you trade, but feel satisfied with your profits.

Accepting losses or moving forward for some trades.
I have this behavior before that is like I am marrying my altcoins or some trades which I always changing my mind where I will cut loss, this is the major mistake I have done before.
That’s why before entering a trade, I always finalize my stop loss and target price.
