It'll better option to go for listed alts or participate into IEO or even in IDO rather than participating into ICO. IDO is so much hyped up and many projects are doing great by doing IDO and instantly listed on uniswap. Though ethereum gas fee is so much high and getting anyone into whitelist is so much hard and depend on luck. But it'll be more poriftable instead of losing precious cryptos into ICO, IMHO.
