Crypto is an unproductive bubble
One of the biggest drawbacks for blockchain is that transactions can&#x27;t be revoked after the fact (with the only exception being costly forks of the entire ledger), and there&#x27;s no additional human oversight (like I&#x27;d get when sending a large amount of money through a bank) to protect me.<p>If someone steals my credit card, I have my credit card company to give me some level of protection. They can block transactions if they think it&#x27;s stolen, and if I report it as stolen I can claw back money from fraudulent purchases.<p>If I purchase something and don&#x27;t get what I paid for, I can contest it with customer service or my credit card company.<p>With crypto, a software flaw used to steal crypto can kill an entire company. They&#x27;re largely powerless to stop it once the transaction has gone through.<p>With crypto, a xss attack or a misplaced password can cost me all of my coins.<p>With crypto, I have to triple check the address I&#x27;m sending coins to because I can&#x27;t undo it.<p>With crypto, I have to spend what&#x27;s sometimes a significant amount of money just to complete a transaction, and transactions can take minutes or hours to complete.<p>I think there&#x27;s a future in crypto but we&#x27;re in the dotcom boom days of it where most of the value is in speculation (and I suppose illegal purchases on the darknet). I&#x27;ll wait for crypto 2.0.
