Hi nostr:nprofile1qqsgdp0taan9xwxadyc79nxl8svanu895yr8eyv0ytnss8p9tru047qpz4mhxue69uhhyetvv9ujuerpd46hxtnfduhszxthwden5te0dehhxarj9eehqun0wehk7um59ehxctcppemhxue69uhkummn9ekx7mp0ggeksn , could you help me find a way to get tBTC? I did research in many places but I found just potential scams or pages that do not work... maybe you got an idea how to get btc for the testnet? Extra question, could you explain (or refer to a post/video/link) the diff between testnet and testnet4? Many thanks in advance :)
