Hello! i am a newb regarding bitcoin and I guess, like everything else in life, your first time should be something to remember. Or not, in the case of a transaction as things should be smooth and unremarkable, without any surprises. I got my email from them with the keys. I haven't touched it yet, but plan to transfer them to my blockchain address.
Right now I don't know if I have to do this or just keep them as is, printed out, as I do not have the need to spend them right away.
Anyway, still learning. Will use their service again.
You should create a paper wallet and transfer the amount to there if you plan to keep the bitcoins for a longer time. Anyhow, congratulations on getting your first coins.
