Investing bitcoins is like investing Gold. always profitable.
No, it is not true, investing in bitcoin is not like investing in gold, as with investment in bitcin you can earn a big amount of profit within a few days(means shortest time) and with investment n gold you will have to wait for months and years to see any increase in price.
though bitcoin price might fall too thus you not only would lose a lot of money but also you would not make any profit out of it in this situation gold would be more profitable than bitcoins
i think that its a good idea to invest your money into bitcoins if you like risky investment options though if you like to play it safe then you should surely choose gold in order not to lose money
