what are your best bitcoin wishes in the coming years?
I wish we see less speculators adopt bitcoin who want to make a quick (fiat) profit and get out. I wish to instead see more people adopt bitcoin who want financial sovereignty.
Do you think that with the lower inflation rate and upcoming halving Bitcoin can finally be put side by side with Gold?
If you mean bitcoin's "inflation rate", I don't think halving is going to change anything about bitcoin to put it side by side with gold. They don't fall into the same category regarding age, spendability, adoption scale or even supply cap (gold isn't as limited as bitcoin).
If you mean the global inflation rate, your question makes more sense since inflation will always push people towards converting their fiat to something that is a better store of value. Both gold and bitcoin are good options for that.
Are there any possible ways that Bitcoin can be regulated without Nakamoto? I think only centralized exchanges will remain regulated and projects like Bitcoin can't be touched. What do you think?
With or without the inventor of Bitcoin, it can never be regulated because it goes against its principles of being decentralized. However, centralized services like exchanges will be built on top of bitcoin and will be regulated.
Will banks and BTC forever remain enemies or something new will come up?
I don't think their position is going to change until mass adoption (which we aren't even close to).
