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.
But is it really worth your time? Wouldn't you earn more by doing either full-time or part-time job? If you also include shit token, you may lose money instead due to TX fee.
