Investing in bitcoin is not a big risk, if the government of different countries are investing in gold as reserves for their national tresury, what do you really think makes investing in bitcoin more risky?

I think you might want to say that investing in bitcoin is more risky because the price of bitcoin is very volatile, well, for now, you may be right, but don't forget that if bitcoin eventually have the same or more liquidity, volume and market cap same as gold, the price will become more stable than it currently is, at that time, a person can sell up to 10 or 20 bitcoins at a go and the price won't show any sign that Bitcoin worth that huge amount was sold, same thing goes with buys as well.

And stepping away from that, I think we are yet to see the future of bitcoin, it is indeed becoming clear and clearer as each day passes, bitcoin is destined for greatness.
