No matter how profitable you are with bitcoin right now, there is no guarantee that it will remain the same in the next months, years, or decade. So always invest at your own risk. Invest on an amount you are comfortable of losing. And when you have established your bitcoin investment, then start to diversify and invest on other assets that you think you have higher potentials to progress later on.
Bitcoin is much in demand right now, but never forget that changes are inevitable. Apply good risk management instead.
