Scam ICO can be in any platform, it doesn't matter if it is in ethereum or NEO, why ethereum has more is because it is widely use by many people to host their ICO, I believe when NEO gain much popularity like ethereum, it will be even worst because it is a free gas platform.
What are you talking about? NEO does not require permits, but it is very expensive to deploy a contract so any fishy ICO will try to avoid it.
What do you mean expensive to deploy a contract on NEO? Isn't it just doing codes like how they deploy code on ETH with solidarity?
I'm now aware they have to pay fine for deploying a contract on NEO But if that makes the fishy team to avoid NEO then they must have foreseen it clearer than Vitalik's team.
