When the bitcoin is donated you will understand yourself if the exchange is kyc or not then you will be asked to kyc. As far as I understand both wallets you can use all wallets for donation are same capacity or don't want to mix kyc and non-kyc coins so using separate wallets for kyc and non-kyc donation can keep donation in different ways.
KYC is very important and it's meant to be passed by people that indulges in crypto activities, this is because there's presence of bots. Bitcoin donation is privatized by those investors and holders, but there should be frequent record of every bitcoin transaction coming in and fro. Bitcoin should be stored in custodial wallets for there safety and ensure to keep the 12 phrase discreet. In crypto, we don't expose ourselves to the society, rather we keep them at distant and also executing more projects to ensure there's probably smooth.
