I have never really been a fan of the stock market but at least at its core it kind of makes sense, being publicly traded gives a company the finances necessary to do huge things. Gains and losses are based on company performance so they are open to some analysis.
The cryptocurrency stuff feels like gambling right now, and if Goldman/Barclays are getting involved in it, it is because they know they can stack the deck.
I think more likely is that the number of places that don't accept credit card of some sort will just continue to decline until it's largely just groups who can't for some reason (low/no connectivity in their operating locations and/or difficulty accessing banking for example). In that environment there's not much that BTC adds to make it a better option than a credit card.
Furthermore for most people even with the lightning network paying with BTC will be like a slightly slower prepaid debit card with less fraud protection and no ability to execute chargebacks because most people will pay out more to vendors than they'll receive in payments in (excepting cases where they're paid in BTC for some reason).
