On the website they instruct you to take your Bitcoins from your coinbase wallet and put them in a second wallet like breadwallet or mycelium wallet before making payment. I downloaded breadwallet and have nothing but problems because it says I have no internet. I read reviews on mycelium and frankly they are scary as s*** people say they just lose coins they disappear Into Thin Air! Who has recently ordered from Pharma? Do you actually have to transfer to a second wallet before confirming payment?
