UK is fine as I have an account though I have only purchased via crypto.com so far. Quiet accumulation then one day I can request a gold bar! One thing I noticed on crypto.com is that the price does not always stay in step with the market price particularly at times of high volatility. It will correct though. It's probably a reflection of lower volume and I doubt it will be an issue when buying via the Paxos website or Kraken.
