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?
I think the most problem when you using bitcoin is not when you buy or sell it.
It is when you use it to send your btc to other wallet address. The transaction can take your time.
This is because the blocktime of bitcoin is slow.
You have to be extremely careful to send Bitcoin to the right address otherwise you will simply lose everything. This is probably the thing that frustrates me most of all.
