If you want to stay safe and 2x your investment, invest in eth, if you want to also stay safe but 20x your investment this year then invest in blockport (bpt)
of course for immediate benefits can be suggested, I suggest to invest in large quantities as intial capital if you want to invest in ethereum. because for the profit is also much obtained when the price rises slightly
Obviously that putting all your money on ethereum or bitcoin is not risky, but if you put all your money on a single altcoin that is a low cap coin, you are risking a lot, maybe you are taking too much risk for a single coin.
