This might be true, good experience doesn't guarantee you in always making profit. This talk is about daily trading in which the risk is very high. If we chose the wrong coins, we might end up taking a cut loss, and we should be ready taking such action. Daily trading usually is theirs who have big fund in their wallet. It means, if you're not, better you don't do daily trading.
