No worries, no altcoins. These are underground P2P apps for bitcoiners by bitcoiners. It's an interim solution for people who live on the bitcoin standard, not waiting for the hyperbitcoinisation. The fiat systems don't even know they're being used. Come to Poland and see for yourself how easy it is to spend sats anywhere right now. It's just a transaction, but there are three sides of a deal instead of two. You have sats and you want goods. The merchant has goods, but prefers fiat. I have fiat and I want sats. Blik and bitblik are convenient solutions that let us make this exchange via internet and LN. For my bank it looks like I bought the goods from the merchant. You stayed anonymous. I bought non-KYC sats. Everyone is happy.
