who would you buy a coffee using bitcoin? dont you have cash, lol but i see your point, your example are too simply not to be ridiculed at, sorry. As for the fees are concern, true, it does make bitcoin fall (partly) though it is not the main reason for this fall on bitcoin, you have to consider the trend which newbies follow. the fees are already there and given, that is how trading goes when you deal with exchanges. maybe the stores in your place only tested bitcoin's capabilities to compete with fiats. they are also experiencing hassles in their own exchange sites, so they stop and the other stores follow. what matters is what you believe, believe in bitcoin and make other investors to rely on bitcoin too. do not post negative stuff like this, the only way for bitcoin to go up again is to keep it for a while and make room for law of demand.
Well part of the reason the banks got bailed out in 2008/9 was because they controlled the payment network for everyday commerce.
Bitcoin was exciting in the beginning because it promised to be an alternative payment network, one that would allow govts to allow banks to fail because they were not the sole payment option.
We're going backwards when you say, why not use fiat. It means we haven't moved forward in the last 9 years.
