THE RADICAL MOVEMENT | $TRM
1,000,000

Tax: 8/8 (4% Autoburn 4% Marketing)

Description:
The radical movement is a new order system that rejects 
government authority and focus solely on community consensus. 

How it works: with the aim of igniting the burning passion of crypto enthusiasts, 
$TRM strategized two-way tax ruling to build a strong independent community: 
1. 50% of tax is depleted directly from token supply circulation. 
The process includes burning the token supply and sending it directly to the DEAD wallet.
2. Once organic community is built and project is stable, 
50% of tax tagged as marketing will be used to 
buy stable token selected by community itself.
