1- ICO
There is a lot of ICO coming in recently, and mostly base on ETH's platform,( ERC20, smart contract). ICO has raise more than 3 Bil USD and that cause the price of ETH rise also. It's very soon that ICO will be put under regulations and rules, and will ETH will fall because of it?
2-Hack
The DAO-ICO, one of the biggest ICO in history was hacked since Hackers found the gap in smart contract, despite the effort of ETH's dev, hackers still got 8.5 mils USD after that. It means ETH still have a gap, failures in technical?
3- Congestion
Just after the Cryppokittes becomes hot, a lot of transaction of ETH was stucked. There is still a lot of ICO incoming base on ETH's platform And can ETH stand with it?
4-Inflation
Don't like Bitcoin, ETH doesn't have the limit of coin, and it may cause the inflation in the future?
Those things just my point of view and some information from internet. Feel free to have a discussion with everyone
