The chance of getting ROI% profit is high by participating on their IDO platform, but to get allocation is hard because is using a lottery system. The more tokens you are own, the more chance you got to get an allocation. One of my friends held "Polkastater" token and tried to participate on their launchpad, guess what? more than 10x tried never getting lucky to win at least one project allocation.
Hmmm same lottery ticket that binance decided to start using on its platform years back with IEO projects? That sucks anyways it's like not everyone will be able to participate and get few part of the coins, shame, this is why ICO was the best, widely open for everyone no lottery kinda thing needed
