Nope,generally one doesn't have to price the accounts.Its quite evident from your post quality and potential activity.Moreover,its really up to the lender what price he sees in the account.You have a YoShit signature,the account is worthless I may add.
To OP, I would be interested in this loan; however others are correct and the account is not worth that much. Do you have any other collateral?
Could it be because once an account is linked to a YoBit account, all future payment for that signature campaigns would not be able to be claimed by the new owner. So it has less potential value as the new owner would not have the option to participate in a popular signature campaign.
