Actually, there are many altcoin choices which are worth buying to get a big profit when the price goes up, and everyone must have a different opinion, because the mind between one person and another is different. and for me, the coins that are good for investment right now are, Bch, Eth, Dash, Btg, and also Litecoin. what I recommend is, it certainly won't be the same as the choices of others, so the decision is in your own hands.
