I think in 2019 more ICOs will appear and more scammers. Because until now no party has arranged or selected ICOs that will appear so that the ICO will continue to appear even though the ETH price is down.
And at this time it's not the right time to invest because the ETH is falling too deep so that it can make us lose.
This is now the new trend in the cryptocurrency...making money from ICO and this trend will continue in the coming years. Just be ready as more scammers will enhance their strategy to lure money from newbie investors. I hope that a better regulation will be implemented to eliminate or minimize fake ICOs to protect the investors from those scammers.
