Do I need ETH to send ERC20 tokens?
I'm trying to wrap my head around this cryptocurrency stuff, and I've come across ERC20 tokens. I've heard that these tokens are built on the Ethereum blockchain, but I'm not entirely sure what that means. So, here's my question: do I need ETH to send ERC20 tokens? I've got some of these tokens in my wallet, but I don't have any ETH. Will I still be able to transfer them, or do I need to acquire some ETH first? I'm a bit confused about the relationship between ETH and ERC20 tokens, and I'd really appreciate it if you could clear things up for me.
