Just to see if I can post anything here at all.
Referring to Scambrain explosion allegation in the HBO movie, I find shitcoins useful in a sense that you can sybil shitcoin networks and get an airdrop, and then swap the shitcoins for BTC.
This is my first ever post on this forum, please don't ban immediately.
Maybe others can share their stories.
If you really have that much time to go on a spree to collect airdrops and then find something that's actually worth swapping to BTC then why not.
It's a time consuming process and also depends on luck because many airdrops are of no real value.
Since it's free money anyway there's no harm in doing so while exploring other options of earning bitcoin.
