You have a point there. After all, bitcoin is a very new asset and still not widely accepted, so there is still a lot of risk, and it would be a bad idea to bet our future entirely on bitcoin.
I don't think Bitcoin should still be considered a new asset. If Bitcoin were to be a person, that is, a foreigner living in a foreign land, 10 years is enough to make it a citizen of that country, which will consider it not to be a stranger any more. So to me, Bitcoin is actually no longer a new asset as far as I am concerned, and if I may ask, how long do you want Bitcoin to stay before you can consider it old enough to be worth your investment or pass the risk requirements?
I hope you know that investment risk can only be managed and reduced, but it can't be completely eradicated no matter which form of investment it is, so the same thing is applicable to Bitcoin. No matter how long it stays, it will only gain more popularity and approval from those criticizing it, and some Bitcoin racists will turn their backs on it and become Bitcoiners, but that will not change its volatile nature, which puts your investment at high risk, especially when you buy at a higher price.
