Mi konstruis aplikaĵon nomatan http://coinwatch.space https://coinwatch.space/eo, kiu helpas homojn spuri sian kripto-monujan valoron, kalkuli impostojn (kapitala gajno), kaj sekvi riskon de prunto garantiitaj per kripto-valuto. #Esperanto #Kryptavaluto #Nostr #Privateco #BTC

After the Ledger breach exposed my home address, I realized crypto portfolio trackers are an even juicier target than a wallet vendor's shipping database — they know exactly what you hold, how much, and when. So I built coinwatch.space with a Privacy Vault: client-side AES-256-GCM encryption, no backdoor, and you can log in with your Nostr key instead of an email. Import trades via CSV without handing over API keys.
