There's no point in doubting when it comes to crypto. There's only two ways on how to get rich in crypto, either being a daily trader or the long term hodler. Being the daily trader, you need to be wise when it comes to decision making specially in selling in an all time high and buying during the bottom price. Long term hodling is different where you're going to hodl your coins for months or even years waiting for the right time and perfect price to sell.
