and you also did a KYC from airdrops, bounty campaigns, and various exchanges.
And on all these activities, you'll only use one address
Then one day you woke up and found out you received 10000 Bitcoin
from a wallet coming from one hacker's wallet who just hacked one big exchange..
And so many people know who you are where you are located and your status in life
because you are using only one address...
So what do you think will happen to you now..
This might very fictional but the possibility is there.
What I'm trying to emphasize is to avoid KYC and using only one address.
You can use mixer apps easily and your BTC's will be untraceable. So it doesn't matter where Bitcoin comes from. It's not that hard to make it untraceable.
