Firstly I see no reason why someone on this forum that has ranked enough to be in a signature campaign would receive bitcoins directly to their exchange address and worse of it all a centralized exchange. -snip-
Sometimes people decide to use an exchange wallet address to avoid fees. As we know, when transactions are busy on the blockchain, we have to spend more money to get confirmations faster. I considered using the same method when BTC fees were over $20 during the BRC-20 boom. I almost did it, but I decided against it because if I used an exchange wallet and the wallet address in my account suddenly changed, I might lose my payment. So, for me, it was better to pay fees than lose everything.
It is not an excuse for them to use the exchange's address and especially when blocks are filled with transaction paid fees lower than 1sat/vb. If anyone thinks that way then bookmark this thread for regular updates:
