I work in the crypto industry right now - my job is to keep bad guys from stealing XXX millions of dollars. I've also worked on a team that has done the tech side of several record breaking NFT's sales. And I've sold my own NFTS for fun, and strangers have bought them (wat!). I'm not a "believer". Crypto is indeed full of idiots - and scammers - and crazy people who will say anything to see the token they hold go up…
I really agree that it's good to go in with a level head. If you highlight the extremes of either "believers" or "non-believers", both sides seem like low effort takes. I bucketed crypto projects into two categories: (1) things that are only possible on crypto networks, and (2) things that people aren't motivated to do on other networks. For example, the US is woefully missing a banking API, especially for consumers.…
The costs come from:
- Opportunity cost of having lots of smart people focusing on cryptocurrency who could have been researching medicine, clean energy, or space tech.
- Money spent on manufacturing and maintaining the cryptocurrency mining equipment. Those factories could be making other products that directly benefit peoples' lives. We currently have a shortage of electronics because of the pandemic. Cryptocurrency mining makes that shortage worse.
- Environmental pollution produced by the power plants used for cryptocurrency mining. For every $1 a miner spends on electricity, the rest of society will pay $N to remove the CO2 later. Also, emissions from coal power plants often poison people and soil nearby.
- Increased environmental destruction caused by digging up energy and building and running more power plants.
The ultimate benefit will not be worth the cost. How could it?
