Cryptocurrency is rapidly gaining ground. Being a crypto enthousiast, I would value this above reg fee because of its future potential. I'd be surprised if the market cap of cryptocurrency as a whole were not to exceed 1 trillion USD by 2020. As it gains ground, the value of crypto related domains will, too.
The question is whether bitcoin will remain dominant or indeed, significant.
I'd hold on to this name for another 2 years.

Maybe some indie game dev might come along some day and put out an offer. Or maybe you'll hit the jackpot when some over the top action movie gets released with said name.
I personally see little value in this domain.
IOSAppDev(com)
This needs to be actively developed if it is to have any value.
It reminds me of domains like html5gamedevs(dot)com, which would have little value without being actively developed.
