Nowadays to produce crypto is difficult, moreover, the market still looks slow, earning income by trading also seems less profitable.
But by being patient and playing with more observance, you will likely get a little profit.
because currently holding is the best choice because the conditions are not profitable to trade, especially for investment in the ICO.
maybe you can add your assets and hold them until the market recovers so you will get a big profit.
I think to trade a situation like now is pretty good. for some assets we can see trading volume increasing. if for investment, I really would never do it if it wasn't for the really good ico. I better hold my money to buy assets on the exchange than I have to invest in ico, which is mostly scam.
