The company that is claiming they will send me the BTC says I am required to pay 0.59 BTC in order to receive 12.4 BTC and that the 0.59 BTC will be refunded with the transfer of the 12.4 BTC.  I received an "Incoming Transaction" which requests this amount with the following wording:

"Required Minimum Hash Power on Reflection ID: 0.598647 BTC"

What doesn't make sense to me is that they are using Lightning Network to transfer this large amount of BTC.  Also I have no idea what Hash Power on Reflection ID means.
