Theres a lot of good coins now especially the coins from Top 1-10 in the coinmarketcap but since mostly these coins are already expensive, I prefer more cheaper coins since it doesnt need for a big capital investment. I really want Ethereum and Litecoin but since they are already high in prices I cant afford to buy many so I go for Trx, xrp and Ada for I am a holder of these coins and I do believe on them. Hopefully these coins will boom this year 2018!
