In general, I agree that ETH is a profitable asset for investing, but I think that Vitalik and his team should work on their product for a long time in order to reduce the amount of commissions, which is one of the most expensive today.
I didn't understand what Vitalik and his team is charging to invest in ETH? If you mean by gas price especially when you trade on Uniswap or other like that DEX's than you have to pay insanely high fee there. If I missed or don't understand you point than explain this in details.
