Your coins.ph Wallet is a hosted web wallet.
Just like other hosted web wallets (e.g. Blockchain.info, Coinbase, Circle, or Hive wallets), you can use your coins.ph wallet to store, send, as well as receive Bitcoin.
You can access your wallet by signing into your account and clicking [Wallet] on the lefthand navigation bar, or going to https://coins.ph/wallet.
You can transfer bitcoin from an external, third-party wallet to your coins.ph wallet, and vice versa.
