Whenever I read about this, I consider that most of us on this forum are guilty of this. We use the same addresses when applying for signature campaign and also our bitcoin addresses has been public. Also, it will make no sense to keep changing bitcoin addresses every other week by sending a PM to the signature campaign manager. What do you say about this. We are vulnerable and exposed.
He was just pointing to privacy which is a good way to prevent someone from tracking our Bitcoin but the problem is all addresses that we use in the signature campaign are always public there's no way right now to make our BTC private because we already posted our BTC address here on the forum and all transaction are recorded on the blockchain even we keep changing our BTC to any signature campaign it's still public unless if we sent the BTC to other address which they don't know if we own that address where it sent to.
