In my opinion, there will be more years to come for its market value to reach 50000 USD since bitcoin is volatile and there are always intances that its price in the market will fall. Also, the market value of bitcoin is still struggling to reach 10000 USD at this moment so surely, it won't be as ahigh as that in just a couple of months. But for now, the best thing to do is to hold and invest more because its value is expected to be more expensive in the future
