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
it will be profitable in the future and as of now people should wait for the market to grow, i am holding only 2 coins in the market and willing to hold for a year because that is investment it should be sit for a months or years to be able to have a profit. Those coins you indicate above are the coins that is good for investment I am trading XRP now and it all went good as of now.
