I am not sure this is a god strategy, I have 5-6 coins, and try not to keep more than that as it becomes impossible to keep following the coin's news.
Is holding up to 5-6 coins only too risky ?
how many do you hold and what is your rationale for that number ?
6 to 10 coins are even reasonable. Considering that coins in trading are very volatile. Sometimes they shoot up, sometimes they dive also. Before you start positioning, things have already happened. So there is a need to diversify your portfolio. Be careful to monitor their movements also. If an All Time High is already broken, you better sell.
