Indeed these are certainly great reasons to invest in Bitcoin. But since cryptocurrency in general is extremely risky (not that is would fail, but that it fluctuates wildly), it may not be suitable for conservative investors. Certainly, for young people, Bitcoin is a certainly an asset that NEEDS to be in one's investment portfolio.
Yes, Bitcoins and other cryptocurrencies are not suitable for people who don't want to take a risk to earn big. But everyone can do it around 5% to 10% of their total investment money can start putting in these crypto currencies. Because slowly crypto markets are picking up and also these things soon or later going enter into mainstream businesses but by then it will be too later to enter and one may miss the opportunity make a good profit.
