..I find shitcoins useful in a sense that you can sybil shitcoin networks and get an airdrop, and then swap the shitcoins for BTC.
That's what I did and I also recommended this to my friends All the airdrops I received from tap to earn platfrom during its heyday I converted or swapped to Bitcoin because at that time Bitcoin is gaining support from then US Preseident candidate Donald Trump.
I made the right choice; those airdrops dropped to zero and Bitcoin reached one all-time high to another.
