Why Choose OKX for Buying Cryptocurrency?
Before diving into the process, it's essential to understand why OKX stands out in a crowded market. The exchange prioritizes security, transparency, and user experience—three pillars critical for any digital asset platform.
OKX has published its Proof of Reserves (PoR) report for 28 consecutive periods, confirming that all user assets are backed 1:1 by real on-chain reserves. As of the latest report, OKX holds over $28.1 billion in supported assets across major cryptocurrencies. This transparency ensures users can verify their funds are fully backed at any time.
Additionally, OKX uses advanced security measures such as:
