I see a lot of people try to argue against bitcoin by saying that it is too volatile, it is too unstable to be a viable store of value. Which in my opinion is just not true.

Given the capped currency supply that bitcoin has, in the long run, it can't be subject to debasement or depreciation simply due to the central bank and/or the government abusing their power of printing more money on demand. Countries like Venezuela, Argentina and Zimbabwe have all experienced this, and at the end of the day, fiat is only as good as the central bank's ability to maintain its value, which I wouldn't trust in the long run.

For bitcoin, there is simply no way of manipulating the supply, and thus, it is a great long term store of value. Fluctuations in the short term isn't really a problem at all and doesn't affect its long term mechanics, although arguments saying that transacting in bitcoin while prices are fluctuating is difficult could be somewhat based. However, that should improve by itself simply by time, given more adopters, and actual acceptance of BTC as a currency imo.
