I think crypto In order to remain the currency market, it will be set to set the limits for ico.
Which tools? By who? And we are in crypto world, who has the right or power to limit ICOs? In my opinion, we should protect ourselves before someone do it for us.
No need to do that.
People are wise enough now and learned from this thing. I doubt it that many are still going to buy with these ICOs. Learning on how big they can lose with these ICOs is enough for them to stay away from it and just start buying coins directly to exchanges.
People are wiser, however, the scammers are also more cunning. Let do more research before joining any ICOs. Better safe than sorry.
