What is the most Frustrating/Annoying thing that you come up against each time you use/but/sell bitcoins?
Do you think it will it ever be fixed?
The most I get frustrated about the fees (not tx fees; the fees various businesses add for their service)
Exchanges get at least 4-5$ when you withdraw Bitcoin. This is a lot for somebody that may want to get 10-20$ worth of Bitcoin and get normally advised to not keep their funds at exchange.
The only payment provider I know in my country which facilitates Bitcoin payments adds some 8+% to the price.
If I want to use "Bitcoin card" the exchange to Euro makes me lose some 2-3% (I don't know exactly, I didn't check lately) and then I may lose some more exchanging from Euro to local currency. The most reputed local exchange still gets some 2+%.
If I want to change between local currency and other country's fiat, the exchanger nearby gets less than 1% fee.
I hope to see one day for Bitcoin too more exchangers (not only in US) and much lower fees. In time it'll happen...
