I agree with you, all transaction has been put in a bottle neck just like bitcoin but has been solve in just a few hours but that was years ago, its 2017 now and still the ethreum network has experience this kind of thing, i dont know what will happen to the investors on ethreum network.
I don't know why anyone is surprised. Ethereum crashed anytime a popular ICO launched on it's network too.
There is no way the network could ever have any working 'dapps' without crashing it too.
Now....imaging people trying to use this network for anything actually important. NOT gonna happen.
All hype, no substance.
That will change with Plasma, Raiden Network and PoS. Is all future growth.
