Diversifying your investment into 10 coins or tokens is a good idea. Anymore than that when you are just getting started will create problems. The amount of hard drive space for 10 coins alone will be over a terabyte.
Bitcoin and Ethereum are both at a year low and I think it is a good time to buy both.
With ICOs, you must choose wisely. Due diligence is key. Do your research and invest in projects that solve the many problems in the infant space.
If you are interested in a unique ICO with existing technology, look into PROTO.https://prototoken.io/This project will be a game changer in the crypto-space. PROTO uses a much more effective data structure and solves the many problems with blockchain.

https://bitcointalk.org/index.php?topic=4511338Diversification of investment is always a good idea if you are planning of pouring money in crypto market that is highly volatile and unpredictable. Diversifying investment provides more security against loss and higher chances of profit.
Number of coins that you diversify your investment in depends on the amount that you are planning to pour in. I too have diversified my investment in BTC and 6 other altcoins that I have chosen after thorough research and study of charts.
