This is for sure a good thing, but here (small city in Italy with 90k abitants) a small bar can make 150 coffees in one morning alone, and I suppose they're talking about the income by all sells, not only coffee (altought they write " coffee").
I love the idea of a small city with a bitcoin working ecosystem, and I think it's possible to achieve, but some thousand of pounds of volume dosen't excite me, because we're not talking about global adoption, but a " btc enclaves". 1% seems not enough...
well lets say its 150 coffee's a day, then we are looking at over 2.5% population bitcoin usage as a minimum, instead of 1%, which is even better.
the other way i see it..
if the UK thinks its 'apocalypse now' by letting in 20,000 syrians out of 65million brits (0.03%)... yes 0.03%
... then seeing 1-2.5% of people not using the british pound and using bitcoin instead should be bigger news than the refugee crisis
and just remember it hasnt really been that long either.. so imagine the bitcoin numbers in 2-5 years time, once all the islanders realise they can detach themselves from the british pound and be more independent
