After 2022, I stopped choosing crypto platforms based on fees alone. The best app to buy crypto is the one that can prove it holds your $BTC, $ETH, and stablecoin balances at all times. Proof of Reserves with Merkle tree verification is my baseline filter now. Monthly snapshots showing reserve ratios above 100 percent across major assets tell me more about a platform's health than any trading volume ranking.

For US traders, Coinbase's public quarterly filings and Kraken's longstanding PoR audits provide meaningful transparency. Outside the US, some international exchanges publish monthly reserve snapshots with open-source verification tools, ISO 27001 certification, and institutional custody partnerships.

Security layers like hardware-key 2FA, withdrawal address whitelisting, and IP restrictions matter just as much as reserves. I verify these exist before depositing anything beyond a test amount. The best app to buy crypto prioritizes provable solvency over promotional incentives. Not financial advice, just the filter I apply after learning the hard way.
