Log in reward bonus

There would be a nice idea adding a log in reward..what do I mean? Loging in first day give u 1 mil...day 2 in a row 2 tonens day 3 in a row engine or car part day 4 3 tokens
But if u fail to log in u go back to day 1 I think this will be nice..I would appreciate considering about it..thanks

This could be a good idea except instead of logging in you could make it that they have to setup their car in practice and then give a daily bonus.

Or do what gran turismo was doing in gran turismo 6. Have a daily login bonus that resulted in your winnings being multiplied by an amount. 110% on 1st login, 130% 2nd, 140% 3rd, (cant find day 4 bonus %) and 200% on day 5. It froze at day 5 so you could not get any higher then 200%.
It would mean that people who just login without doing anything will got a higher percentage of not much, whilst the people who play and do well because of this will be rewarded. Hopeful this may increase the converserion rate of downloaders to regular players
