They were basing off the extraction price. a good starting bid IMO would be about 65B
a rule of thumb is 1bil=1mil SP but usually 1 bil less… unless you have some expensive ship skins or implants etc that can affect price somewhat.
also people may price it based on what skills are trained, and what they are looking for in a char, ships etc.
The sale of characters with SKINs is permitted, and prices of characters can be adjusted as seen fit by the seller to reflect the value of their skin collection on the character being sold.
Items cannot be listed among the character’s valuable assets, only skills, implants, SKINs, and reputation. You are buying/selling the character ONLY and nothing else. Ships and items can be readily bought or sold on the market for ISK.
