Very risky move considering that ada don't have even worked product. For now, changing something which works well for something which can work well as the first one, not a great idea.
price of bitcoin is very low. In this situation, the ethereum can become the first. I think that the ethereum has enough high potential to take the first place in a coinmarketcap.
It'd hard to imagine that Ethereum can bit in price bitcoin. Ethereum maybe can bit in capitalization but not in price. Even now when bitcoin around $6000 ethereum was max $600 which ten times lower than bitcoin.
Can you provide any link on the big recourse which can prove that everyone talks about "big money come to cryptocurrency"? And Even if they come who want to buy on top only hamsters.
