there is no difference between bitcoin's PoW and Ethereum's when it comes to things like ASIC and hash power,... and i think you are confusing ASICs with bitcoin-specific-ASIC.
Are you sure that we are talking about the same thing? I was referring to Bitcoin's SHA-256 ASICs and Ethereum. I think it's quite a big difference between Bitcoin's PoW and Ethereum's - referring to their algorithms - and Ethereum is moving into the other direction to be even more different (ASIC resistant by ProgPoW). so what you are calling advantage here is just ethereum being far behind in the evolutionary stages that bitcoin passed many years ago when the first ASICs for bitcoin were created.
Yes, it's possible that ETH can also be mined with ASICs but it's not very popular. Right now ETH is using Ethash algorithm for their PoW and Ethash is not completely ASIC resistant (that's why it was possible for Bitmain to launch Ethash ASICs). Ethash is not ASIC-friendly, it's rather GPU-friendly. But the ETH miners voted to implement ProgPoW a few months ago which will be even more ASIC-resistant and that decision was part of many controversial discussions. I did not follow the discussions closely but AFAIK the main reason to implement ProgPoW were interests of the GPU suppliers and similar benefits for the current miners. 
I can imagine that ProgPoW will be the last change before ETH will switch to PoS.
So if you say that it's theoretically possible for ETH to change their algorithm, both could be the same but I think that won't ever happen.
Doubling price is not at all realistic solution because rewards are ultimately going to become zero in next century.
By logic of doubling prices , In next 40 years ,BTC should cost more than 7 million USD per BTC. I just wish if it can be true.
Yes, that's true. Long term the only rewards for miners will be transaction fees. Until then, it's still a long way to go but I'm sure there will be a good solution. By logic of doubling prices , In next 40 years ,BTC should cost more than 7 million USD per BTC. I just wish if it can be true.
