Why come up with such imagination when you know that Bitcoin can never be a stable coin ? It's not possible that Bitcoin will become a stable coin in the future so this kind of discussion does not really contribute anything to Bitcoin and we know that no body will want to hold a stable coin for length of years knowing that inflation will affect it, that already defeats the definition of a profitable investment and since most people are holding Bitcoin to hedge inflation, so if it becomes stable, people will go for better options.

Do you know that some people don't trust any stablecoins because they are all centralised ?
DAI is decentralised but not well embraced, Bitcoin if stable coin and it's decentralised, people will want to use it as their dollar.

Your argument makes no sense. If it would be fixed it wouldn't be bitcoin, but something completely different all together. You might as well ask if people would hold DAI.

I think what you want to ask is, "would you hold bitcoin if it wasn't so volatile?". Or that "would you hold it if you knew it wouldn't go much higher than this?". Or even better: Would you still USE it?

And answer to that is, probably yes. I was using it when i thought it would crashing back in 2014, when i thought it might die. I didn't want to hold it though, which was a mistake in hindsight, and which i learned absolutely nothing from.

This is a simple question that I would give a direct answer. No, I won't invest or hodl it and my reason is this... If bitcoin seize to increase and become a stable coin, it will lose its advantage of being a store of value. Like if inflation will eat up the value of the bitcoin that I'm hodling then what is the reason for using or hodling it? It is as good as fiat whose future value is usually reduced with inflation overtime. So instead of hodling it, I would choose to invest it in a physical business so that it can also generate income on that part no matter how small it is rather than being held in stagnation while inflation will keep raising and falling value of purchasing power at the long run. I could instead invest it in buying of land which has more and better prospect for profit with time.

A lot of people buy stable coins and they have their reasons why they are holding stable coins. This means if the Bitcoin price becomes a stable coin, people will still buy and hold because there are different reasons why people are buying it, and it is not just about the value it has. People who care about the value may not have an interest in holding Bitcoin, but those who find it interesting beyond the value of Bitcoin would still want to have it.

The reason why people are rushing into investing in Bitcoin is because the price is increasing and the could get some profit from it when ever there is bull and this seems to be the most interesting part of Bitcoin.
If it price become fixed people will the buy Bitcoin but it won't be at the rate it is today depending on individual, and purpose of investing, I am sure at that point many will buy as a store of value and not for profit making. It may also drop the decentralization purpose of Bitcoin, which means the authority controlling it will have to decide when to sell, how to sell, what price to sell, and who to sell to. This will disqualify the original purpose of Bitcoin and makes no difference from fiat.

If Bitcoin's price hadn't risen, even like stablecoins, then I'm sure Bitcoin wouldn't have grown this far. And I'm not sure I would have even known about Bitcoin. That would mean Bitcoin is similar to fiat. Meanwhile, the only fiat accepted in my country is the Rupiah. So, I wouldn't risk my money on another fiat stablecoin if it didn't offer positive returns.

This alone is clear. Bitcoin is truly far more developed because of its many positive aspects. It's not just its decentralization and anonymity that are its positive aspects. It also has a value that increases over time. This is also one of the big reasons why so many people are interested in Bitcoin. It's so valuable. Its value has risen significantly. And we know that the price will also rise much more in the future.

For sure I will still hold bitcoin even if the price should remain stable, however the urge to buy more bitcoin won't be there especially if the price should remain stagnant. The main reason why people invest in bitcoin is to make profit and this is through price appreciation, however bitcoin offer freedom such that we can be able to control our own money. Profit alone isn't the reason why people invest in bitcoin but without the price of bitcoin appreciating it will definitely affect my decision.

I don't think bitcoin in the first place would have gotten these so much attention if it was a stable coin and I'm sure you ought to know this and you should also know that one of the major reason why people are holding bitcoin the volatile nature and regardless how volatile it might be, it still has a very limited supply and holders are always optimistic that it will attacks in a new higher price always no matter how low it dips.
Which means that, the volatile nature of bitcoin is the sauce and juice of it.
