Bitcoin is yet to be stable and is definitely risky for a huge investment.
With that being said, it is a growing currency, growing in popularity and notoriety.
Its future seems to be a good one.
the thing is... when bitcoin will be stable the price will be too high to invest and acquire many bitcoin, instead right now that there is more instability the price is more affordable
think about this for a moment...
Yes, this is absolutely true! And this is not only Bitcoin. Everything functions this way. In bouncy times, there is a huge opportunity to profit and also to lose a lot! But that's why you need to know what you are doing of course!
On the opposite, during the calm times there is not to many possibilities for big earnings! The same will be with Bitcoin in the future!
