In the mystical halls of Hogwarts, where magic and cryptocurrency coexist, our cool non-custodian Swagrid found himself caught in a rather peculiar situation. One day, as he was patrolling the castle grounds, he stumbled upon the mischievous young wizard, Monero Malfoy, attempting to trade Slytherin Shitcoins for pristine Bitcoins.

Swagrid, with his keen sense of justice and a touch of cool authority, approached Monero Malfoy with a raised eyebrow. "What's this, Malfycoin? Slytherin Shitcoins in exchange for Bitcoins? You know better than to dabble in such dubious wizardry!" Swagrid exclaimed, his beard twitching with a mix of concern and disappointment.

Caught red-handed, Monero Malfoy tried to conjure an excuse, but Swagrid was having none of it. To teach Melvoy a lesson about the importance of clean and ethical magic, Swagrid devised a unique punishment. Instead of heading to Dumbledore's office, Monero Malfoy found himself tasked with a different kind of magic – cleaning and maintaining the Bitcoin mining devices tucked away in the Hogwarts cellar.

Swagrid, with a twinkle in his eye, explained, "If you're going to dabble in the magical world of cryptocurrency, you need to understand the ins and outs of proper mining. Bitcoin, my young friend, is the gold standard, and you'll be helping me ensure the smooth operation of our mining endeavors here at Hogwarts."

And so, Monero Malfoy, under the watchful eye of Swagrid, embarked on an unexpected journey into the world of Bitcoin mining. Armed with a mop and a newfound appreciation for the intricacies of blockchain, Monero Malfoy cleaned and maintained the mining devices, learning valuable lessons about the importance of transparency and integrity in the magical realm of cryptocurrency.

As weeks passed, Monero Malfoy not only gained a deeper understanding of Bitcoin but also developed a respect for the ethical use of magic in the financial realm. Swagrid, ever the mentor, nodded approvingly, "Remember, Monero Malfoy, in the world of crypto, it's not just about the spells you cast but the integrity you uphold."

And so, under Swagrid's guidance, Monero Malfoy emerged from the Hogwarts cellar not only with a clean Bitcoin mining setup but also with a newfound commitment to using his magical skills responsibly in the cryptocurrency realm. The castle echoed with the hum of mining devices and the whispers of ethical spells, as Swagrid continued to impart his unique blend of coolness and wisdom to the aspiring young wizard.
