█████████████████████████████████████████████████████████████████████████████████████████████████████████████████████████
HELON is a project that combines HEX and ELON. 

FIRST OFF, FUCK THESE RUGS !!!
TO MANNY CLASSIC AND INU RUGS TODAY.
OR A FUCKING DEVs BLACKLISTING HONEST BUYERS, JUST HORRIBLE.
DEV 99% TAXING  HONEST BUYERS PURE FUCKERY!!!!
PAYED CALLS THAT PROMOTE/CALL SCAMS TOKENS AINT HELPING ASWELL.
WHILE SAFU PROJECT GET NO ATTENTION.
ALL IN PLAIN SIGHT!!!!
FUCK THAT!!
LETS CHANGE THIS PEOPLE!!!!!

Tokenomics:
Name: HEX ELON
Symbol: HELON
Total Supply : 1,000,000,000
NO PRESALE OR AIRDROPS
Tax : 6% buy and sell
Max trx : 1%
Max wallet : 3%

FACTS:
Taxes on this contract can't be higher then 6% so no 99% tax bullshit.
max trx can't be lower then 1% so no fuckery there.
LIQ will be Locked and contract will be renounced so nothing can be changed.
Before renounce max wallet and trx will be set to max so everyone can ape as much as they want.
There will be no TG by DEV..community may create as u choose, if u do add me @HEXELONETH.

lets moon this HEX ELON.......Hard!!!!
