It becomes more and more effective with the arrival of new investors. So the next efficiency boom may come with a new wave of investors.
It's not getting effective, the market's just getting bigger and more people are just getting in so it creates an illusion that the effectivity is getting bigger and bigger even though it's just the same. Bitcoin is already very effective so I don't think that it's gonna go beyond that.
Bitcoin has proven very effective for 11 years, I hope performance will continue to improve, now many stock companies and other large companies are continuing to develop bitcoin so that in the future it will be more effective than now.
