BEP20POC.pegout_submit(uint256) (#795-822) uses timestamp for comparisons
Dangerous comparisons:
- (block.timestamp - arr_pegout_submit[arr_pegout_submit_key[i]].reg_date) < 86400 (#801)
Avoid relying on block.timestamp.

Different versions of Solidity is used:
- Version used: ['^0.8.0', '^0.8.9']
- ^0.8.0 (#6)
- ^0.8.0 (#32)
- ^0.8.0 (#116)
- ^0.8.0 (#145)
- ^0.8.9 (#501)
Use one Solidity version.

- delete arr_staff[i] (#632)
BEP20POC.pegout_submit_cancel(bytes32[]) (#883-896) has costly operations inside a loop:
- _unlocked_POC_total -= arr_pegout_submit[del_id[i]].amount (#889)
BEP20POC.pegout_submit_cancel(bytes32[]) (#883-896) has costly operations inside a loop:

BEP20POC.pegin_reserve(uint256[],bytes32[],address[],uint256[],uint256[]) (#901-921) has costly operations inside a loop:
- arr_pegin_reserve_key_last += 1 (#917)
BEP20POC.pegin_run(bytes32[]) (#971-991) has costly operations inside a loop:
- _unlocked_POC_total += (arr_pegin_reserve[id[i]].amount + arr_pegin_reserve[id[i]].fee) (#981)
BEP20POC.pegin_run(bytes32[]) (#971-991) has costly operations inside a loop:
- _fee_income += arr_pegin_reserve[id[i]].fee (#982)
Use a local variable to hold the loop computation result.

Pragma version^0.8.0 (#6) allows old versions
Pragma version^0.8.0 (#32) allows old versions
Pragma version^0.8.0 (#116) allows old versions
Pragma version^0.8.0 (#145) allows old versions
Pragma version^0.8.9 (#501) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.10 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.
