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.
If I want to invest in ICO I make sure the ICO is good enough and innovative in project development that is done and communicative to all people and participants so we know the progress so we are safe in investing in their ICO, but if want to be safe and long term I choose Bitcoin.
I agree with your opinion. investing in ICO is nice and promising for your life, but if you do your first research you may get a lot of benefits because if you do not do research, you may be exposed to fraud in it. I advise you not to miss it if you want to participate in ICO.
