There are alot of things to be learnt from discussions here and the least and most of recurring of them all is the gist concerning privacy and decentralization.
It baffles me when I see old members of the forum repeating the things that is preached against over again. Many of us here are aware of how some users were flagged a certain time by an exchange due to a mixer campaign that got involved with some dirty doings. We have to play smart and try to protect our privacy by all means.
Centralized platforms can freeze your money any time they find something suspicious with your transactions. This would be a good example for those who would still repeat same act. It just never ends..
The reason why some of the Old membersz added their exchange wallets address to their signature payments, mostly comes from the headeck that comes with moving Bitcoin sometimes when the meme pool is congested and transactions fees get skyrocket..
They do this with aims of avoiding the high fees and delayed transactions, but what they must know is that, as they keep enjoying the easy exchange of their payments to Fiat, they should know that they are losing privacy, freedom and control of their assets at any point in time.
