btc as mean of pay do you use it ?

[cmdline]

last month in general was almost quadruple in btc price, but thats where it escapes my logic as it being currency since volatility is so insane,i like that theres means to pay someone other then card or western union or likes,but this new craze with cryptos becoming speculation item , drives them away from whatever it should even be called currency,since by the time one can now get x amount of btc you can easily see shift of 100-500$ up or down, which renders it hard to use it.My hope is that eventually some crypto comes out as is tied 1$-1crypto or close enough as actual currency but not speculative stock on which someone can make millions.
