Bitcoin will never be as "stable" as something like the USD — heck, even gold isn't that stable. It's just that as time goes and as more and more people use bitcoin, bitcoin wouldn't be as volatile as it is today.
Just look at what people are saying right now, experts say that people shouldn't hold USD because inflation is just 5% a year, but imagine if you have bitcoin that can go down like 5% a day because some whales sold it. It will be problematic for people to use it on a daily basis because of that.
Because you don't buy your bitcoin to immediately sell it in a day. Usage-wise, probably wait for it to appreciate by a few points before actually using it. There's a reason it's almost never recommended to go 100% on bitcoin — always leave room for your fiat currency
Sure, I can provide some additional context on the factors that could impact the stability of Bitcoin as a currency.
One of the key challenges facing Bitcoin and other cryptocurrencies is the issue of scalability. As more people begin to use Bitcoin, the network can become congested, leading to slower transaction times and higher fees. This can make it less practical as a medium of exchange for everyday transactions. There are ongoing efforts to address this issue through upgrades to the Bitcoin network, such as the adoption of the Lightning Network, which aims to increase transaction speeds and reduce fees.
Another factor that could impact the stability of Bitcoin is regulatory developments. Governments around the world are still grappling with how to regulate cryptocurrencies, with some countries taking a more permissive approach and others imposing more stringent regulations. Increased regulation could potentially help to reduce volatility and make cryptocurrencies more appealing to mainstream investors, but it could also reduce the relative anonymity of cryptocurrencies, which is a key selling point for some users.
Finally, the overall global economic climate could impact the stability of Bitcoin. Economic instability or uncertainty could potentially lead to increased demand for Bitcoin as a store of value, but it could also lead to increased volatility in the cryptocurrency markets.
Overall, it's difficult to predict with certainty whether Bitcoin will become a stable currency in the future. However, ongoing technological advancements, regulatory developments, and shifts in the global economy will all play a role in shaping the future of cryptocurrencies.
