Just my guess, the flip is sudden and taking over almost all crowd sale
When over year ETH will be filled by scam ICOs people will go to another platform lets say Waves/Ador this time. Nothing last forever
And ETH have to has final exit pump for insiders soon so expect "cool news" ba bla next BTC BigCorps joining ETH to conquer world. This time we will pass BTC in PnD
and that will be exit strategy for devs for a while to capitalize ETH since pump cannot last forever.
ETH is trending for promotig many scams and people like because new idiots are not aware of risks behind.
Most people will learn HARD way that 95%+ ICOs will fail or be scams at end.
In real world startups which wins are 1/1000 so here will be the same guys.
Most of those decentralized application will just fail.
Same as failed many premined IPO ICOs on BTC.
