Because a trusted business, will do like you shared, take care of their reputation seriously and won't let invalid scam accusations harm their business reputation.
Because many people don't own their houses so companies have to provide users more options and I am sorry, but did I miss that Chips.gg only allow users to submit house/ real estate ownership proof for KYC?
I really believe Chips.gg team don't require it as a mandatory condition and only condition for KYC.
In some platforms, they provide other options like bills (electricity, water, internet bills, and the likes) for basic KYC. With higher (advanced) KYC and business /corporate accounts, there will be more complex requirements and documents for KYC procedure.
You're correct—most platforms, including Chips.gg, typically offer multiple options for KYC (Know Your Customer) verification. It's highly unlikely that house or real estate ownership is the only option available. Many platforms accept utility bills (electricity, water, or internet), bank statements, or government-issued IDs as proof of address or identity. Advanced KYC for higher-tier accounts might require more documentation, but basic KYC usually accommodates users without requiring homeownership. It's always best to check directly with the suppor team for the specific documents they accept for different KYC levels.
