Hi, Sent this as a PM to Jonathan but thought it may also help others.

Hi Jon

Im wanting to purchase Leonardo.

I started the process then i got to the Bitcoin Payment section.

I don't have any funds in a Desktop Wallet, only on Bittrex.

Now i can copy your BTC Address and then send the required BTC.

2 Questions really.

As BTC is 'anonymous' how will you know its me that has paid and grant the license?

Also im a little confused over the fee on Bittrex, when i send will it deduct the fee from the amount or add it on. Dont want to send it short and end up paying 2 X Transaction Fees.

Hope you get what im  trying to say.

Matt
