I think any top 10 coins will be a good investment now, but I especially like EOS. She compared to other coins most of the good prospects to grow. So far, the only one has practically solved the problem of scalability.
EOS is a great moving cryptocurrency in this year. But I recommend Bitcoin and Ripple because both are different platform so surely it will make good profit in future. I think top 10 altcoins are just a long term investment so we should searching for some other altcoin because many cheap altcoins are make good profit in quick period.
