buying now is profitable because crypto prices are still low and we can easily choose potential coins like BTC, XRP, ETH, BCH, EOS and stellar which I consider to have a good and profitable future for its users
Making my choice, I will concentrate on the cryptocurrencies which are in the top-20 (even in the top-100). I have already invested in Cardano, EOS, NEM, NEO, Etherreum, Ontology, Qtum, and TRON.
