Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
the problem with beetcoin [sic] is [..] that you don't know if you have enough money with you to be able to get off the bus, because, unlike a bus, beetcoin [sic] doesn't ask for your fare to get on. It lets you on, but if you don't have enough change on you? Have fun riding the bus. For the rest of your life 
Dynamic fees predict fare based on current demand. If demand increases in the interim from boarding to alighting, then RBF gives you the option to increase your fare. These mechanism mitigate the problem by and large.
Yeah, that dynamic thing did some bombass predicting for Miss Coin:
I like some things in life to be as simple and idiot-proof as possible, money is one of them.
I do not care to be my own proctologist, my own brain surgeon, or my own bank. I do not want to think about opting into RBF (I have no idea how to even do that, how should Miss Bit done it from her wallet? Link?) and adjusting fees for that pack of smokes I'm buying, and when I pay for a beer, I don't want to worry about fat-fingering an extra digit or including unconfirmed inputs.
