For me, i am really into Bitcoin and Ethereum only because these are the top two cryptos that i believe will always dominate the cryptoworld. I am happy i have both of them in portfolio and i will keep on holding it for long.
Me too, if I invest in the long term, I would choose ETH and BTC, because these two coin is always a big coin and it is hard for us to lose money if we are still patiently holding. Only in 2019 will this price increase two more coins.
