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.
Well mate, in depends on what type of investment you want to invest. Bitcoin is a secure investment in a long term. It give you more profitable earnings and the risk is slight only. But if you want to earn in a short period of time or short term investment. You can invest your a good altcoins. Just make sure that you will research everything about it before investing.
