Why are you selling it so cheap? That's half of the price I've seen them go for.
That's my first sale and I made some discount on the first account. When it's sold then I'll sell accounts with a price calculation formula. Something like that;
member & lower accounts: "activity * 0.75 mbtc" (if there's potential activity it can go up to 0.9 mbtc )
for example: 98 activity Member account: 73,5 mbtc.
full member: "activity * 0.9 mbtc"
for example: 140 activity F m acc: 126 mbtc
sr member: "activity * 1.1 mbtc".
hero: ask for price.
Ps: those are just examples, before making any deal ask for price & availability.
