/**

Welcome to the Tax Game; here you are competing against one another to who will obtain the keys to the tax wallet from which you can claim your rewards. 

When you make the biggest buy you are now the leader in the Tax Game where you begin to accumulate all the fees collected from the tax. 

However, once someone buys a bigger bag than you, they are now the leader and so you are dethroned. 

If you happen to sell whilst you are still the leader, the game resets and awaits for the next biggest buy to become the leader. 

If you sell any tokens at any point in time, you can no longer be the leader and accumulate fees from the tax. 

Every hour the game resets and a new leader is crowned when the next biggest buy comes in. 

Enjoy the game, Play Safe, this is the Tax Game
