If Bitcoin is more stable it will be easier to use, the question is , will this ever happen?
This is possible, it is for majority of the full node users to accept the dev changes but I don't think this will ever be done since its irrelevant especially now.
The fact is no currency is entirely stable and an example is our fiat currency naira.
Bitcoin cannot be made a stable coin since, stable coin are pegged to fiat currency or asset since it came to solve a problem of the traditional currency which is the fiat currency. It can't be decentralise using this means since it will be depending on the price of such currency or assets.
Bitcoin uses the proof of work mechanism in order to function well were by Miners rewards for mining a block is being halved every 4 years and the next one is around April this year by which the miners will be earning about 3.25 bitcoin for successfully mining a block and also Bitcoin as a maximum of 21 million supply and currently about 19 million has been mined already, the price has to constantly increase, so that these miners can continue to validate blocks and not being choked up by expenses.
The volatility of Bitcoin as made bitcoin price raise significantly as time goes by and many bitcoin investors has been able to have a better standard of living through it
