I read the information on the website and that I understand
1.this list on btc address from section - donate now
2.wait end
and it's all? how do I then get their XEL if I'm not registered and do not leave your e-mail for communication? (Will transfer funds to blockchain.info)
I myself will have somewhere to seek public key? or it will come somewhere? and what I do with it then
If you have the private key of the bitcoin address you sent the money from, this should be enough.
They will be sending XEL to the equivalent address on the XEL blockchain, generated by those private keys you already own from the btc blockchain.
They will also (hopefully) make it easy to import those private keys into the XEL client and then you'll see your coins once the client syncs.
At least it better like I'm describing be or my donation went down the drain.
