Hmm, So Op you are having concerns about the global mass adoption of Bitcoin, well that is not possible at least shortly, also with the current network fees, no one would love to buy the Water bottler after paying the skyrocketed network fees. Lightning Network has some exceptions for that.
TBH the adoption Op you are talking about at least I'm not even expecting the next Halving era, it will be after a few more havlings, and at that time maybe there can be an efficient solution for Bitcoin's network scalability issues. But Bitcoin is still the mainstream and for the altcoin's shit i cant say anything.
adoption of crypto is in continuous motion so there's no hurry for it to be mainstream. as long as the market exists and people are supporting it, the chance to go mainstream is always here. but saying, it will never become mainstream is an understatement.
why i think it is slowly going mainstream?
- big companies/stakeholders are buying their own stash of crypto
- top personalities like elon musk is getting involved
- banks are trying to integrate CBDCs in their financial system
- approval of ETF
- online/offline merchants are adding crypto payment
- increasing number of crypto users and so as crypto investors
- financial platforms are considering their stake on crypto
- countries are making bitcoin as legal tender such as El Salvador and Central Africal Republic
