Right now you can buy tokens using crypto currency. We accept Ethereum (ETH). You need to transfer ETH to the ICO contract address provided to you after you have registered. Please do not send any ETH from Exchanges - that is, do not use wallet addresses provided by Exchanges like Coinbase, Bittrex, Poloniex, Kraken, etc. 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. In a while, we will be also be accepting Bitcoin (BTC).
