Yes.
A few concerns with this token -
1) Vitalik organization is running out of fiat money as he admitted himself and he will need to start dumping his large bag to pay expenses
He's already sold enough OTC in the current bull run to keep the foundation running for years.
2) You think Bitcoin has scaling problems , Ethereum's blocksize is already over 10GB and no one is using it. Even if they "sharded up" and pruned the blocksize they are going to have much larger problems because there currency isn't a currency but fuel for cpu cycles, thus a popular DAPP would both drive up the cost of cpu cycles and clog the network
3) 12 sec blocktimes is absurdly small and leads to too many orphans or forks. This is why Monero devs are increasing from 1 minute block times to 2 or more
They know, the difference is that they're not complete wackos, so they're prepared to implement the solutions that are available.
4) Lack of practical use case of any Dapps , mainly a novelty right now.
They mainly don't exist right now.
5) Once ethereum switches to PoS, there will be strong incentives to simply fork the coin to either create a sidechain or clone with the same properties but better security because the fuel distribution can be bootstrapped like clams as proposed by æthereum. Losing PoW will remove any advantage ethereum has over other ethereum forks/clones. Why would anyone want to pay for ethereum fuel when they are given free æthereum DAPP fuel and than subsequent fuel purchases are both more secure and less expensive?
The PoS gamble is definitely a big one. But if crypto goes mainstream, the one that doesn't burn the energy of a small country may have the upper hand publicity-wise.
