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?
Yes, indeed. Bitcoin is very appropriate on EXTRA income not a MAIN income, like as you said it is very risky and unpredictable. If you lean on bitcoin only, maybe your income won't flow continuously. It is better to have income in a physical way and bitcoin as your extra income.
