Full heartedly agree with all of these appraisal prices.
Was going to post mine but they're pretty much exactly the same as yours.
I'd maybe put a little higher on the IG, that's it (IMO).
The lead singer of Attila is loaded with money. Has his own clothing line. He'd pay top notch for it if he enjoyed using Kik (not sure). So it has a chance for a high profittable value. Or a good account for a fan. Just my opinion, though.
Crisis- $70 (if you don't sell it soon) and $100 (if you sell it around now)
The reason I say that is because the new method will fuck the instagram market.
