Actually it is a good idea but you will need to wait really long fo bitcoins to reach 10k$. It would take several months or maybe years for bitcoins to reach there. Investing all your money for such a huge long term investment may not be good but you can always try to invest some shares of your profit for the future as bitcoin will surely bloom up.

Holding coins for such a long term needs a lot of patience and if you have that amount of patience then for sure you can be a millionaire in the future once you see bitcoin above 10k$. Even i invest some amount of my profit for my future and always i think that i will have a bright future with bitcoins.
