Which coin gave you more return? Investment on Alts or ICOs or BTC?
I don't invest in ICO's so that's a crossed out choice, alts are good investment but only those coins like ETH. But the coin that gave me most return none other than bitcoin, this is the reason why I still holding it.
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.
If you are not good in trading with many coins then stop doing it and focus more on where you are gaining by holding bitcoin.
