If we are already upgrade to level 15 and want to go to level 20 , we need to paid 51.30 $ more ?
This is correct, the cost would be higher for non vip players.
A new ad system has been added to the game. You can now display your own ads directly in game on a weekly basis.
Cost per ad per week is roughly $1 in any currency offered in game. You can add as many ads as you'd like for a maximum of 25 weeks.
To view or create a new ad click on the Main Menu and select Game Ads. You can view how many clicks and views your ad receives at any time via this page.
Nice, I've been waiting for this feature - do you have any traffic stats you can share?
For the ads themselves I don't track exactly who clicks them, just when the ad is loaded or clicked it will add it to the ads existing stats.
For traffic stats for the site itself, I only tally up the amount of views the sites get which is displayed at
http://cryptodatabase.net on the right side and resets daily.
It would take up too much database space to keep full records of these, 100-200k records per day. I'm trying to avoid anything that creates too much space as I'll have the issue I had before with my backups on the vps not being able to create full copies.
