I agree with MJ. I really love a silver round from ballet, but have no opinions about Kaspa. Unfortunately the completionist in me will pick up one of these for the collection, but I would love to see these in BTC more than another coin. I fully understand Ballet's position, they have made cards for multiple other cryptocurrencies and have made a silver card for LTC blocks, so this really is not a far stretch, just want them in BTC also!
