Idk much about drivechains but I do know that allowing shitcoin alternatives on bitcoin is the dumbest idea I have ever heard. The affinity scam that is shitcoins will be easier to sell to unwitting degenerates - “This is just like shitcoin X but it’s built on the bitcoin blockchain!” Anytime theres a rug or one fails, it will tarnish bitcoin’s reputation. We don’t need other coins. Bitcoin doesn’t need change. Bitcoin is hard money and that’s more than enough.
