Token seems to be legit.

Contract locking ether found:
Contract TokenProxy (#113-174) has payable functions:
- Proxy.fallback() (#21-97)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

Contract name (YVS.Finance on BSC) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

TokenProxy.implementation() (#168-172) is declared view but contains assembly code
Ensure the attributes of contracts compiled prior to Solidity 0.5.0 are correct.
