Honestly I always expected that what needs to happen is figuring out something much better than crypto itself. I am not talking about defi, I am not talking about altcoins, I am not talking about a brand new blockchain or a new way to use blockchain, I am talking about something brand new that is much better and has no connection to bitcoin at all.
Remember just 10-12 years ago there was no bitcoin at all, it didn't exist and one day satoshi did it (whoever he is) and in the end we have it now and there are thousands of copies of it that tries to be a better and bigger version that failed. If you want bitcoin to be not going higher, you could have something totally better and at that point we would all switch to that and leave bitcoin that could stop the increase.
