Some exchanges like localbitcoins allow you to convert physical cash into bitcoins. This offers the person converting the money peace of mind as its very unlikely that physical cash being converted to bitcoins can ever be traced back. But, some other exchanges require identity confirmation and as such. Some people prefer anonymity and the peace of mind that comes with it and are willing to pay a little bit extra for that. Having said that, the difference between many of the competitive online only exchanges aren't that big.
Yes we have one of these in the UK where small seller sell direct to buyers
bitbargain.co.uk/buy
if selling you have to pay them a registration fee of about $90 and it seems to only have
a about ten sellers but i thought it was a manual type system were they set the price in the
morning as off they go to work.
My evil mind had the plan of front running them and buying from them if the live price
shoot up before they noticed it but alas it was not to be, prices are linked to live prices
and go up or down during the day.
Longer term we should be buying or selling back to cash using what we call miners today
instead of brokers even if we have to have a 3rd party a bit like ShapeShift to deal with USD/GBP
payments and then these miners could offer a useful service instead of earning money from a
pointless race not that we would need 200,000 of them
"the difference between many of the competitive online only exchanges aren't that big"I've seen over $700 difference on a single BTC today between two exchanges but i grant you that one being GDAX is
ten times bigger than the other one.
