Which coin gave you more return? Investment on Alts or ICOs or BTC? I have been holding BTC for a long time and I want to expand my portfolio. I have ETH holdings as well. I tried trading with many coins but never made of it. The reason I don't want to invest on alts is that those companies will create FOMO and make people buy and after buying you will be rekted.
Yes if you want to safe investment btc is the best choice do you have in cryptocurrency, but you can't get a lot of profit when invested in btc. But if u dare to take a risk, investing in alts or ico is very profitable if your lucky!
