ICO with hype is bad usually so avoid them if you see them. I usually join their chat group, telegram / slack to see how many people in thechat room. If it's too much then i will avoid it, i also check youtube videos, if too many youtubers promote them it's bound to get overhyped.
why do you say so? i have always thought that hyped ICOs will get a larger exchange price bec of high demand vs supply.
From my experience, a lot of hype will generate a lot of demand of course, but the supply itself is very big because the project want to collect as much money as they can so it will even out in the end. And another cons is they attract a lot of people that are new to investment and flippers. If they decided to give bonus, people will sell it immediately causing the price below ico, not to mention bounty if there's any. Flippers want to sell immediately because they want to jump into another project making the supply > demand, and the panicing new investor will also sell theirs at loss for the final touch.
