Turn your Rupees into magic numbers.The seller will spend some of the Rupees buying GPUs to generate some more magic numbers, and some he'll spend on holidays and parties and property.
Underpinning crypto is *that* transaction. Behind all the swaps and coins and NFT pass throughs, that is what is happening.
There is no money there. The claimed value it has, is the value you were dumb enough to pay for it, and that money is now in luxury goods in some conman's new villa.
To cash out, you need to convince some sucker to pay more for the magic numbers than you did. You need to join the con and be a better conman than the people who convinced you to pay money for magic numbers. You need to pump and dump too, and be a smarter pump and dump-er than the conman who sold you that crap. But of course, it's *their* market, they can dump earlier than you, and your pump just helps them dump.
