You have to spend more times for analysis price action and fundamental of each crypto, currently there are some altcoin was going up to 100% just in 1 or 2 days, and this good situation to make good profit. To earn maximum profit we should more focus, keep patient and set target profit monthly and avoid greedy.
well, in crypto trading, I'm also not very talented. the thing that I feel most often is when I sell the altcoin that I have, the price tends to rise. well, but I'm grateful, at this time I have avoided so many great losses.
