Isn't that is what Bitcoin all about? (a speculative asset) and a currency of course. Actually it is a currency as a main but it's just that many people are treating it the other way. I wouldn't blame them because Bitcoin's value is increasing consistently. Who wouldn't want to earn a decent profits easily anyway?
That would be an inaccurate assessment. Bitcoin is a speculative asset because it ticks a few boxes, volatility, investors intent to make quick profits by purchasing and exiting in a short time frame, and are generally non productive assets. You think Bitcoin would increase in value consistently, but that is not guaranteed by anything but it is just an observation from a trend. We should never invest just because it seems like it is a trend.
Bitcoin is a currency, but it is also a speculative asset. They aren't mutually exclusive.
Investing is risky but a serious investor knows and accepts this already. Even those who aren't that serious and just rush, can take it as well, because they already buy it anyway, though some of them can only regret it in the end, especially if the final outcome is not successful. With what is said earlier that Bitcoin can provide decent profits, it is actually a big help for those who are living below the poverty line. If the country's own currency is not performing well, I think Bitcoin can also be used as an alternative to them.
Again, wrong assumption made. If it were to make any significant difference, then it would probably be them investing their entire lifesavings in. If Bitcoin drops 10%, 20% of value overnight, it would be terrible for people with such a high exposure. For people living under the poverty line, they probably wouldn't want their money to be stuck in Crypto when the market goes down.
In between stable coins and Bitcoin as a currency means for cross-border payments or transactions, Bitcoin is the winner here, because we all know that stable coins are centralized and a lot of factors can interfere with us. It's so hassle. Stable coins still has their own edge against Bitcoin and that is they are very stable.
Conversely, stable coins are better for them. Stable coins have a constant value while having the same characteristics that enables speedy crossborder transactions. Sovereign funds or even retail investors are smart enough to put only a portion of their asset exposure to Bitcoin. There is no guarantee that Bitcoin would grow in value consistently. Facilitating cross border transactions would be far better in that regard.
I don't believe people who need the money should dabble in crypto solely because the risk is too big.
