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 = 21.000.000.
Max Trx = 420.000.
Max Wallet = 420.000.
BUY/SELL TAX = 6% (Buy&Sell) 1.80% Dev fee & 4.20% BTC Rewards.

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 30 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 69K MC.
* I hope the community makes a Telegram (I will join at 100K MC).  
* DEXTOOL LOGO SOCIAL UPDATE at 150K MC.

I only get 1,80 % Tax 4,20 % goes back to You the Community.
No Dev Cash Grab, but a Dev Who Cares About the COMMUNITY
Let's Moon this, because the more volume we get the more BTC 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 SHIBETOSHI SWAP at 250K MC
* Build/Release SHIBETOSH LOCKER at 350K MC
* I will use 0.5% of my collected taxes for fast track CMC & Coingecko at 669K MC
* Start building SHIBETOSHI ANTI RUGG SYSTEM (ARS) RUGGSCANNER/TOKENSNIFFER and HONEYPOTCHECKER at 750K MC
* I will Dox at 1 million MC, I'm not a coward like SATOSHI

We don't need big paid Influencers or big Marketing,I rather the community  get all the rewards! RIGHT????
4.20% BTC Reward on a 6% token is INSANE influencers will shill this for free!!
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.
SPREAD BTC 4.20 % BTC REWARDS 1.80 % DEV TAX
LETS FUCKING GO SEND IT

Greetings,
