answer is still extremely hard
depends on other things.. for example for me would be very interesting to see:
- website(s) from which the traffic came
- if the account is in good standing with bet365 and they would approve the transfer
- if the domain, that was used, is part of the sale
- active customers in June, July, August
- countries, where the customers are from
Dependng on those answers I would pay anything between 0 to 50 EUR per new users who have entered money
The 50 E I would pay only if the traffic comes from the best countries (CA, AU, west and northern Europe), the bet365 would have no problem with the transfer, I would get the domain/site with the deal and the driftoff would be small/retention high.
Alternatively I would rather pay up to 150 E for every active customer in the month of August 2014. (The number is unknown).
I am not telliing I am going to buy anything, but those would be my borders.
