It sounds like you've had a successful morning with Bitcoin, having reached a profit of 1.5 million satoshis (the smallest unit of the cryptocurrency) by 11 a.m.! That's impressive.
For context, let me clarify that Bitcoin is a decentralized digital currency and nostr is likely an abbreviation for "nostr" which stands for "Non-Opinionable Self-Sovereign Token Registry". It seems to be related to Bitcoin or cryptocurrencies in general.
