In any case you should not keep large bags for you in such an unreliable place.
I believe that it is better not to earn some of the money than to lose all of it.
Why do you consider BSC to be dangerous? I think that all blockchains can have vulnerabilities, so in this sense all blockchains can be considered dangerous. If you are talking about its far-fetched decentralisation with only 21 validators, then we just have to hope that these guys will not give us up.
Personally I consider BSC to be quite safe as devs constantly work on this issue.
