When trading cryptocurrencies, focus on the leaders. Only trade the leaders, not the lesser coins, because when the market rises, the leading coins surge the most, and when it falls, they resist the decline the best. Don't hesitate to get in; trading is often counterintuitive. Don't buy just because a coin has fallen a lot, and don't avoid buying just because it has risen a lot. The more you hesitate to buy, the more it will rise; the more you are eager to buy, the more it will fall. The strong stay strong, and when trading leading coins, the most important thing is to buy at high levels and sell at even higher levels.
