I have a dell computer right now that I can turn off and crypto is still making me money sir. Almost no electricity required except turning my computer on to check how much I’ve made lol. I could buy a $500 laptop and make great money from crypto. Mining is becoming obsolete. Proof of Work is being phased out, Proof of Stake is already in effect with most blockchains out there. Bitcoin will continue to be mined until all 21 million BTC have been minted. Until then, private companies are indeed buying up the supply, but there are no two “Chinese companies” that own a majority of BTC. one, a Chinese company holds the most Bitcoin out of any private company, but it holds only 140k BTC out of the 18 million circulating. Binance holds the most BTC in cold storage, they hold over 200k BTC. ETFs, more notably Grayscale Bitcoin Trust holds over 650k BTC. More ETFs will be approved maybe even this month and the supply will diversify even more. Show me evidence of these two companies that hold a majority of BTC. It is all on a public ledger. Until then your spouting non sense that you probably read on Yahoo Finance two years ago when China controlled over 50% of bitcoin mining. China banned BTC. They banned mining. Why? Because they copied the tech, made it, and are banning all use of any crypto in China so you have no choice but to use their new digital currency they’re releasing (what a shocker, they copied Google, YouTube and Twitter over there and banned use of those platforms). If you don’t hold a BTC or aren’t in any form of crypto ser, ngmi.
