I am a stellar lumens investor and also a developer, I am trying to build apps and I am trying to think though those questions:
I am wondering, if I transact xlm for bitcoin through stellar network, do I have to setup any bitcoin account first? How about USD, any bank account I have to setup first ?
A following question would be if I bought BTC through XLM on stellar network, will this transaction need to go through the bitcoin network to confirm? If not, how to bring other asset (stellar) into stellar network and how to bring them out?
