Why not? 2017 was the explosion of ICOs and cryptocurrencies! However, it died in 2018. And in 2019, back to the IEO trend, cryptocurrencies have asserted their position in the market, bringing great profits to investors who trust for startup projects.
I dont think its back by an IEO thats was different and we all know that this trend will end soon. More of the project now are making thier own exchange so they can start making IEO with that exchange . The problem if there are many of them want it also then mostlikely the hype might end earlier than expected.
It depends on the investors, IEO projects on shit exchanges more likely not interested for investors and the result is also same as shit ICO. But if the project held IEO on big exchange like binance, people will hunt for it.
So, the reason why cryptocurrency is not as boom as 2017, i think the investors are much smarter right now for choosing which project worth to invest, not like in 2017 when every project is success at the beginning but dissappear after it enter exchanges
