$10k for 1 Ethereum? I dont think that would ever happen. Ethereum does not grow that quick to reach 10k in 10 years. It took three years to increase ATH from 1400 to 2000, and now it looks like Ethereum has run out of power to grow. If the story repeats, than in about 3 year Ethereum would cost $3k, and by the end of 10 years about $5k, but only if they would fix fees issues and release some major upgrades (like Ethereum 2.0, but not like Constantinople).
It's true that ethereum won't get into that price level until solving the current gas fee problems, but it's just temporary IMO. As long as bitcoin's on the action and alt season isn't finished properly, etherem might hit $3k pr more within this year instead of having high gas fees as DeFi hype is still on track. TBH, it's now totally depend on the success of ETH2.0 , especially on the implementation of sharding chain. Though good news about ethereum might pump it into half of those high price target.
