I follow the basic rules on investing, which is not to put all your eggs in one basket.
I have 50% invested with Bitcoin and the rest are equally divided with the top altcoins though I limit my holdings up to 5 good coins only so I can maximize its potential. If there's a way to participate with some Bounty, I'll grab that opportunity and take profit from it, I also practice reinvesting where I don't spend my profit because I believe it can be more worth it if I reinvest it.
