I think bitcoin is really a good investment for now, but I don't think it is a good idea to put all your investment in bitcoin or crypto currencies since it is unpredictable and very risky to take. For me it's still better to start your own business than depend your future in bitcoin investment.
What do you think guys?
This forum is full with advice that your should invest only that money in bitcoins that you are ready to loose. I suggest not investing anything more than 20% of the savings and that also if you do need this money in short time. As you said, the prices are very volatile so after your investment prices may drop considerably. If this happens, your money will get stuck in this investment as you will not be selling your holdings in loss. You must keep good amount of savings as bank deposits. These will give you some interest and you can easily withdraw the money in case of emergencies.
