I can't think of a better Bitcoin-only platform for stacking sats in the UK than nostr:npub1ex7mdykw786qxvmtuls208uyxmn0hse95rfwsarvfde5yg6wy7jq6qvyt9.
It's extremely convenient, because you can:
• buy/sell as little as £0.01 at a time
• setup hourly, daily, weekly, biweekly or monthly DCA with no fees (after min. 1 week of DCA)
• withdraw Bitcoin on-chain for free (min. 75,000 sats)
Are you aware of another Bitcoin-only platform in the UK that offers this much?
