AMYF [Amyfootball] Token

Amyfootball.amyBHashAlgo(uint256) (#135-138) uses a weak PRNG: "dataBll = uint256(blockhash(uint256)(_blocknumber)) % stModulo (#136)"
Amyfootball.findBlockWinn() (#140-143) uses a weak PRNG: "dataBll = uint256(blockhash(uint256)(block.number - 1)) % stModulo (#141)"
Amyfootball.supporterShouldGoContrat(uint256) (#228-247) uses a weak PRNG: "require(bool)(uint256(blockhash(uint256)(_checkBnumm)) % stModulo == 1) (#232)"
Amyfootball.amyContratPrizeDist(uint256) (#250-308) uses a weak PRNG: "require(bool)(uint256(blockhash(uint256)(_checkBnumm)) % stModulo == 1) (#253)"
Do not use block.timestamp, now or blockhash as a source of randomness

Amyfootball.supporterShouldGoContrat(uint256) (#228-247) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(amyStakeDetails[msg.sender]._stakebeginning + stCancel > now) (#231)
- amyBlockChecker[finalBlock]._bNoww + 1800 < now (#234)
Amyfootball.amyContratPrizeDist(uint256) (#250-308) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(amyStakeDetails[msg.sender]._stakebeginning + stCancel > now) (#254)
Amyfootball.supporterWantsToLeave() (#323-329) uses timestamp for comparisons
Dangerous comparisons:
- require(bool)(amyStakeDetails[msg.sender]._stakebeginning + stCancel < now) (#325)
Avoid relying on block.timestamp.

-require(bool)(nprizeDetails[amyCheckP()]._ifEarnPrize == false) (#255)
Amyfootball.amyContratPrizeDist(uint256) (#250-308) compares to a boolean constant:
-require(bool)(nprizeDetails[amyCheckP()]._ifShouldProcess == true) (#256)
Amyfootball.amyContratPrizeDist(uint256) (#250-308) compares to a boolean constant:
-require(bool)(supporterTime(msg.sender) == true) (#251)
Amyfootball.supporterWantsToLeave() (#323-329) compares to a boolean constant:
-require(bool)(supporterTime(msg.sender) == true) (#324)
Remove the equality to the boolean constant.

Pragma version>=0.5.16<0.6.9 (#2) is too complex
solc-0.6.8 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.
