Mixing up KYC and non KYC coins? It's all cryptocurrency. You should really only be worried about receiving coins that come from a darknet market, OFAC sanctioned addresses, or from a OTC russian exchange. That will get your coins locked if you ever move them to an exchange without many hops.
What he is worrying about the chance of Him being monitored by the government as he wanted to have a complete privacy in which I thing
many of us wanted to achieve.
you have your answer mate , though am still confused for your complete reason stated above this post but i will respect that and yeah while I also don't trust government that big but nothing I can do but to follow the rules because I am a citizen .
anyway good luck to your donation business mate , and hope you will grow a lot in keeping those coins and may have privacy in all your spending .
To OP, you don't get to choose who can send to an address, anyone can as long as they have BTC and the address, you no need to worry about receiving if it's actually donations and not just a coverup or laundering the money to avoid taxes, right?
But you can stop using them if you want to, by using coin control feature that can be used to freeze specific UTXOs.
Maybe he already have His answers because never that he posted here again .
