Binance, okex, houbi and several other IEO launches from the top exchanges actually don't force people to participate there, and hold their tokens. But it is a rule that for each IEO participant must hold a number of their tokens to be able to participate, and if you don't want to, you are not forced to participate there either. I think so, anyone who wants to participate then follows the rules and for those who object then go and try to find IEO on another exchange.
Yes, we have to follow the rule, this normal, but what if the rule is not fair, why you forced me to buy and hold your token to participate, this not fair.
It caused by that can increase the price of the token that already created by the exchange site itself. I know if this is not fair for you, but that's the rules.
Some people have been doing it rather than investing in an unknown project that runs on the crap exchange site. Holding your token doesn't mean if you can participate in the IEO instantly.
Remember an exchange site like binance has already used a lottery system.
The participants who elect to participate in IEO will have determined after the result of the lottery will be out.
The exchange site is also taking advantage of the users too.
But again, if you are interested to participate and just buy that and if you are not even feeling good and it's free for you to not obtain the token.
