Vitalik needs to do something to speed up the platform. Blockchain is constantly overloaded with 50k-60k transactions in the queue. There is no way to spend a cheap transaction quickly.
PoS, Plasma, Sharding...all good for scaling but yeah, ethereum's devs better speed their development. And by the way, where is the Raiden network? They had an ICO but I don't see it used as a second layer network on Ethereum, it was just a scam or is it being developed ?
