Shuriken Coin is a token on Binance Smart Chain boasting a number of impressive features. It is the first token with a Black Hole design that exponentially cuts the total supply in circulation by massive amounts. Shuriken combines this with an innovative Auto-Liquidity feature that increases liquidity of the token rapidly.
shurikencoin has massive decentralization on a scale rarely seen in other tokens.
Combine these three together and you get a power house token out of the hands of anyone, except the community as a whole

Pragma version0.8.9 (#3) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
