Maybe $.01. Everyday there is a lot of transaction going on so they can still take a huge amount from that. I know there is a few millions of people now using bitcoin. I bet they get much more than they need and there's no need be greedy.
Well for me even if it goes to around 0.5$ it would still be reasonable and a lot cheaper than other transactional fees. That's the good thing with btc and i think it's one of the things that will make btc one of the major transaction forms in the future
In most situations, that fee would be
much higher than any other normal transaction fees. Visa I believe charges 0.2% of the transaction plus 1 pence (UK, about 1.2 cents). It's great if Bitcoin is used as a store of value and is used for investments - spending 1 Bitcoin or more the transaction fee would be very low. But for any normal transactions that make up our everyday lives, the transaction fee is far too high. The problem is how the Bitcoin fee is based on the number of bytes rather than being measured as a percentage of the transaction, meaning that small transactions are difficult.
