Crypto casinos safe for AUD conversions?

Crypto's ace for anonymity, but those conversion hits can sting—lost 5% on one site's ETH-to-AUD swap last year, ouch. Now I prioritize exchanges baked in with low spreads. Explored a few, and Digits 7 Casino keeps it simple: direct wallet connects for ETH, BTC, no extra charges on deposits, and fiat withdrawals land in AUD quick via bank. Their slots use RNG certs you can verify per spin, which adds trust—tried Gonzo's Quest, fair drops every time. Poker's solid too, with Hold'em tables that aren't shark-infested for casuals. One niggle: crypto bonuses are slot-only, but the 50 free spins offset it nicely. Overall, feels secure without the paranoia. How do you handle tax reporting on wins? Any tools you swear by?
