I'm with you Bro! Since BTC seems already at its peak when it comes to price. I also prefer to invest my money on ETH, more cheaper, the better. You may also try to look on other cheaper Cryptos in exchange, I'm sure you will consider them because of their potential.
ETH is cheaper then bitcoin. ETH is said to have good growth this year. This would encourage you to invest in it. Etherum network is working strong to get it's crypto Ether reach Everyone. A decentralised currency which would reach minimum $2k by end of 2018. Please do ahead and invest in ETH.
