The answer is simple, we value your privacy much more than the disrespectful Tinder.
Have you ever realised that you are not lured into falling in love with a girl or guy but also lured into giving away all your information including locations,
interests and jobs, pictures, music tastes and most importantly who you dated to one single app.
Tinder knows your sexual preference, your fear and your weakness even more than yourself.
Can you imagine what will happen if this treasure trove of data gets hacked,
is made public or simply bought by another company? There is no difference between being seen naked in public or can be even worse.
That’s why we present you the Tinder Inu, A on chain dating app service.
The only information we take will be your wallet address and that’s all.
We won’t know your sexual preference, your favourite positon or your darkest secret.
Secure and confidential. Join us if you want to see a more secure and privacy-respecting society.

The number of crypto investors has increased rapidly recently due to the wider application of blockchain technology.
However, how many of you really understand the history of cryptocurrency?
I bet you won’t even know who Satorshi is and how great he is as a kiddo.
Let’s tell us the story of Storshi and express our greatest gratitude to the establishment.

We seek to create a different project where people have a voice and a vote on the important decisions of the project.
We will create strategies in order to facilitate interaction between leaders and holders,so that a multidisciplinary team is created with people who add value to the global brand that we plan to develop.
The only cult that sticks together. We all love one thing: being a degen with diamondhands.
Strong cohesion: The community decides every move, there are no leaders

Capture the Flag
▶ If you make the biggest buy (in tokens) you will hold the Flag for one hour, and collect 4% fees (in ETH) the same way marketing does.
Once the hour is finished, the counter will be reset and everyone will be able to compete again for the capture of the Flag.
▶ If you sell any tokens at all at any point you are not worthy of the Flag.
▶ If someone beats your record, they steal your Flag.

Myōbu are celestial fox spirits with white fur and full, fluffy tails reminiscent of ripe grain. They are holy creatures, and bring happiness and blessings to those around them.
With a dynamic sell limit based on price impact and increasing sell cooldowns and redistribution taxes on consecutive sells, Myōbu was designed to reward holders and discourage dumping.
1. Buy limit and cooldown timer on buys to make sure no automated bots have a chance to snipe big portions of the pool.
2. No Team & Marketing wallet. 100% of the tokens will come on the market for trade.
3. No presale wallets that can dump on the community.
Token Information
1. 1,000,000,000,000 Total Supply
3. Developer provides LP
4. Fair launch for everyone!
5. 0,2% transaction limit on launch
6. Buy limit lifted after launch
7. Sells limited to 3% of the Liquidity Pool, <2.9% price impact
8. Sell cooldown increases on consecutive sells, 4 sells within a 24 hours period are allowed
9. 2% redistribution to holders on all buys
10. 7% redistribution to holders on the first sell, increases 2x, 3x, 4x on consecutive sells
11. Redistribution actually works!
12. 5-6% developer fee split within the team
