I remember when sending $10 worth of crypto cost $5 in fees. It was ridiculous. Nowadays, there are so many efficient blockchains that make micro-transactions viable again. I mostly use Algorand and Hedera now for small transfers. They are fast and virtually free. For a list of the most affordable cryptos, see here: https://swapspace.co/blog/crypto-with-lowest-transaction-fees It’s a good reminder that not all crypto is expensive to use.
