/**

Hi DEV Here,

So, I have been sitting on the sidelines watching the market.
After some thinking I decided on leveraging the move in market, which led me
to create a safe community rewards token with low tax.

This is an experiment for me so I hope you all are ready and can handle this.
Look at these Tokenomics:
Supply = 1,000,000,000
MaxSupplyTX = 2%
BUY/SELL TAX = 5% (Buy&Sell)

I will be observing from the outside as I want this to be driven by the community!

My promise to you the Investor:

* Contract is safe and will be locked for 15 Days and ownership will be transferred to a dead address.
* Contract Trx and Wallet size can't be lower than 2%, and taxes won't be higher than 6%.
* I will communicate on ETHERSCAN.io.
* Website will be built at 50K MC.
* I hope the community makes a Telegram (I will join at 100K MC).
* DEXTOOL LOGO SOCIAL UPDATE at 100K MC.


No Dev Cash Grab, but a Dev Who Cares About the COMMUNITY
Let's Moon this, because the more volume we get the more ETH we Spread.

* I will buy back with at least 0.3 % of the taxes.
* I won't Sell any tokens but will burn them.
* Liquidity will be locked for 100 years at 200K MC

Way forward:
* Release BELLA SWAP at 150K MC
* Build/Release BELLA LOCKER at 350K MC
* I will use 0.5% of my collected taxes for fast track CMC & Coingecko at 400 MC
* I will Dox at 1 million MC, I'm not a coward like Ryoshi

We don't need big paid Influencers or big Marketing,I rather the community  get all the rewards! RIGHT????
We want organic growth, share the message!
Get all your friends and family involved, even your wife's boyfriend.

This is not a scam, so don't listen to fudders that just want you to ape into their scam project.
If you investors Don't Ape into this one maybe you like to be RUGGED.
I hate ruggers but I also hate mindless sheep investors that ape in Rugg/Scamcoins.
Be smart about this and invest in a token that's built for the community by a dev that likes safe
and honest projects.

CREATE THE HYPE
BE SMART FOLLOW THE HYPE
SEND THIS SHIT
LET THE FOMO BEGIN
FUCK THE SCAMS& THE RUGS.
LETS FUCKING GO SEND IT

Greetings,
BELLA team.
