Ive been using wirex card for quite a while now..its a visa enabled card that gives me access to fiat currency easily...they charge around 5% on exchange bitcoin to gbp and its free to used on transaction but do charge... i think off the top of my head..£2.50 on cash withdrawals...
off the face of it, it seems cheaper than coinbase to buy bitcoin aswell but havent tried as yet..
Looks cool !!
