Looking for simple "investment" advice

I have around 650$ to invest each month. Right now I'm looking for a decent strategy to invest into cryptos.

I've made a list of all cryptos I'm interested in. So far that's a total of 11. I already hold 4 of them (60% BCH, 5% ZEN, 5% FCT, 30% ETH)

List: BCH, ZEN, FCT, ETH, XMR, NEO, GAS, XRP, DASH, NEM, OMG

Would you split the monthly amount into a variety of CCs, would you just pick one coin each month and go from there?

Looking forward to your replies.
