How to Buy Onyxcoin (XCN) with 21X Diamonds (21X)

To buy Onyxcoin using 21X Diamonds, first, find a cryptocurrency exchange that supports the XCN/21X trading pair. Create an account, verify your identity, and deposit your 21X into your exchange wallet. Locate the XCN/21X pair on the trading platform and place an order to exchange your 21X Diamonds for Onyxcoin.
