The only way to get people to stop worrying and shying away from Bitcoin, is to banish the volatility aspet of it, naturally.
I put emphasis on the word "naturally" because you cannot force a monetary process to establish itself in a few short years. The price and users must gradually reach an inflection point on their own.
It is similar to implementing the Euro as the official European currency. By no means were the governments rushed to scrap their central bank currencies, they were give ample time (about a decade or two IIRC) to phase it in, in stages.
So Bitcoin, and anything that wants to follow it in market capitalization, must be introduced to the public in phases, which could take a very long time.
The rest of the altcoins that do not stabilize can disappear (e.g. Solana), I have no pity for them as they only serve to give larger cryptocurrencies (and crypto in general) a bad name in the news.
Yes, I agree with you on the bases that you can not force a monetization process to be stablized over night. But removing volatility side of bitcoin is something that might have issue because even my country's currency as it is now, it is unpredictable. And that is already stable currency talking of bitcoin which is not stable at the moment and I doubt if bitcoin even be stable because bitcoin is not controlled by Central Bank of a country whereby it tells the sub bank to obey their policies. Yes if the volatility can be vanished naturally then bitcoin at that point becomes stable but at what point do you what bitcoin to be stable? Because people predict that they want 1 bitcoin to be $100+k and others even predict more so with this I think the volatility side of bitcoin is undiscussed as for now. Even the rising and falling aspect of it is a benefit to some people. Some people make profit when it is in the bear Market and others make profit when it is in the bull market. That is why it is only those who understand bitcoin can make Investment. Anyone that scared to invest in bitcoin is not conversant user of bitcoin. Bitcoin is meant for everyone as it is in fiat currency but everyone is not meant for bitcoin.
