Adding indication in lottery section of the amount of cake has been spent

Perharps its good to have historical data for every wallet / user to help monitors the amount of cake that already been spent in the lottery section.

For those who been participating in lottery will be allowed to claim rewards such as points or NFT.( even better both)

this just a simple idea perhaps can be implemented:

1. those who has spend 10 CAKE in lottery entitled claim 10 points & COMMON level NFT
2. those who spend 100 CAKE in lottery entitled claim 100 points & RARE level NFT
3. 1000 CAKE level entitled claim 1k points & EPIC level NFT
4. 10k CAKE = 10k points & LEGENDARY NFT
5. etc
