It would be not that bad if you are believing in Bitcoins and that is because there are now a lot of people that is going to have some Bitcoin and you also can see that it is becoming more popular.
But of course it is hard to know what the value will be and that is also the only problem that we have.
Its true! No one can determine the value in the future that is why by investing in bitcoins is very risky and we know for the fact the huge risk means huge reward, and as a believer we should be rewarded in the future if bitcoins will have a good success.
That is right. Investing in the bitcoin was very risky in 2010. The price was below $1. But the price now is much higher.
