You're right (to the OP) that WA and CO would have more uses for names like this one, and CA is next, so the market will get much bigger. But I agree w/Varlin, right now mid $XX is probably a good est and you should go by that if you're thinking that renewing it will be being worth it. Unless you can make $ in monetization. And as a name PotBus.com would be better as you know, although yours is cool for some dispensary or store in those states, developing a website I'm not sure...
Also, remember that people are betting big on this wave expanding and more states following, so the easy money at resale and the best possible names are probably kinda gone by now....ie a lot of decent/good mj/pot domains are for sale and the best ones were already regged. But if you have $ to keep it, waiting longer for things to heat up in this area, then cool (also try parking it instead of a sale page, it may pay the ren fee lol...)
