When can you see your PAY tokens?
The PAY tokens will be released 48 to 72 hours after the token sale.
You can use any wallet where you hold your private key. However, your wallet might not be able to show the token, which also means you cannot trade the tokens from there. So what you would then need to do is insert your private key in a wallet that can (f.ex. MyEtherWallet). But the tokens would definitely be there.
You can check your token balance on the Token Sale website anytime under “Check your token balance” with your transaction ID (TXHash).
