For those of you looking for an easy way to purchase bitcoin, in the mycelium wallet app, there is a service under buy/sell called Glidera.
https://www.glidera.io/ Glidera connects to your bank account like how coinbase does but deposits the coins directly to mycelium. It gives you total control of your coins unlike coinbase and its owned by Kraken, which has some of the best exchange rates there are.
