OP is right. Nowadays people started investing money in bitcoin. I also invested some money in bitcoin hoping that in future , its price will increase with time. But I have to say onething .Dont invest too much. Invest what you can afford to lose.Because its price is highly volatile and dont know what will happen tomorrow. Its price can increase or drop. Just like gambling. So be carefull while investing.
It's right, nobody knows what will happen tomorrow, Bitcoin price can go to the moon, but can go to the hell also and we can lose our investment. For who doesn't have much money to invest or can't risk money, try to work on the internet for Bitcoins, this way you aren't using your monthly income, so you aren't risking the money you need to buy primordial things during the month.
The only thing you can't do is to don't invest in Bitcoins, invest any amount, but invest.
