i don't know about "crypto world" but it is a very good thing for bitcoin at least because of a couple of reasons.
the stability will make the newbies who wanted to become rich with bitcoin overnight to leave the market. in other words the weak hands who FOMO buy and PANIC sell are flushed out of the market and market is cleansed. so the volatility will be reduced even further.
all this stability will make bitcoin be a currency more as people have always been complaining about it and saying it is the reason why they don't use bitcoin as a currency, now they wouldn't have any more excuses.
But if those people leave, will it not be bad for the crypto world because then there will be less users? You are right, though. If the price of bitcoin stabilize and perhaps the price will rise only gradually unlike how the price changes now, then perhaps those who wanted to get into bitcoin will be encouraged to finally use it. What do you think?
That's price stability and IMO, that is actually great since merchants would somewhat reconsider in accepting bitcoin as a payment option. Number one enemy of merchants when it comes to accepting bitcoin is the price volatility. They are afraid that they would lose profits if they hold on to bitcoin for long, and securing a third-party payment processor would also cost them some $$$ on the side. Needless to say, the stagnant price would urge merchants to accept it and see whether it will be better for their business or not.
I was thinking about this, too. If bitcoin price stabilize then perhaps the merchants will start accepting bitcoins. It could very well be the safest way to pay for expensive purchases, right?
