Everyone in the cryptocurrency world hopes to strike it rich someday. Whether or not that can occur through legitimate means in quick succession, will depend on how the markets evolve. It is a more valid approach than hoping to find a fat Bitcoin wallet on an old hard drive discarded by someone. The chances of that happening are slim to none.

In an ideal scenario, said wallet would contain dozens of BTC, which are worth quite a bit of money at the current price. In the real world, however, the chances of that happening through legitimate means are nearly zero.
