WPR is on Idex blockchain exchange. Very easy to join, and then send ETH to your main wallet (address found via your account icon). You need to send US $150 plus enough to cover fees, as the minimum order is that. Then transfer the ETH to your Idex Trade Account wallet (leaving some in your main wallet to cover fees) and you are away. This is a centralised exchange that lets you trade in real time, putting it all on the decentralised blockchain in due course ... so your ETH is available within seconds.
