Hello
I'm relatively new to the world of cryptocurrencies but this project sounds very interesting to me.

I already read the guide how to participate on page 18 but there is something I'm not sure about (sorry if it is a stupid question)...
In the guide you wrote I should transfer the amount of BTC I want to spend from my wallet address (I use the electrum wallet) which I have registered as receiving address (step 4-5 in the guide). But in my electrum wallet I have 20 receiving addresses listed and no idea how to choose from which one the wallet should send the coins. Would you still recognize me as sender of the coins if my wallet uses another address than the registered one (step 4) or is this a problem?

Thanks for your help:)
