There's nothing you need to do.

Bitcoin's a currency one cannot buy anything with and its current "value" derives from its "reserve currency" character for people in poor countries (arguably a good thing), speculation, scams and criminals.

Its upkeep is really expensive energy- and hardware-wise. If there ever comes a situation where mining is no longer profitable, its value will drop to near zero, because trading it at scale becomes impossible...

I prefer shiny rocks as an investment.It gives few % return in a decade, which is great. It's been here for thousands of years. not some scam thing like Bitcoin

It's not a scam, the banks are. That's what it's for and its purpose, to counteract the corruption of centralized banking cartels. The wild west was a bit unruly too, but it wasn't a fucking scam.
