#Safemoon is taking 10% in both directions(sell/buy), 5% of which is provided in the liquidity pool and 5% is distributed amongst stakeholders - your stake grows over time and it adds a bit different dynamic to the system.

What I find amazing, is that the system compels you to hold. Why? Well, from the moment you bought the token, in order to have an even trade, the price has to either increase by more than 20%, or you'll have to wait a bit until you compensate the initial loss.
