Spreading your coins is very good idea.
I recently put a LOT in to a particular coin and have regretted it about a week later, but all a learning curve, who knows, you might be right to pick that heavily.
Spreading is al good and dandy, problem is you get spread too thin and even if you win, you win peanuts. Select 2 max 3 coins you think have a role to play in the future society and all-in on them.
