So it will be problem and problem....and trust gone. Remember, bitcoin value only about trust and faith. If this keep happening, people wont use it anymore and decrease value.
Not everybody use bitcoin with huge transactions. Often they use to send 300-1500$, which it doesn't make sense to spent 15-50$ on transactions fee. And they have to wait few hours or days to get their transactions confirmed...
Except there no alternative, yet.
