Hi!
Tokens swap will occur when the ETH transaction is verified on the ETH blockchain, which is normally immediate. Token swap via other crypto-currencies will take at least one working day.You need to transfer ETH from your personal Wallet (for example: myetherwallet or imToken). This is because PGT will be swapped directly to the same wallet as ETH.
Gold-backed PGG tokens will be given after the end of this ICO.
