A few points:
- Anonymity and decentralization are complimentary both are important and decentralization helps anonymity.
- "Non of above". Typo
- "Do you have one (or more) bitcoin address which you regularly use? Be careful by bitcoin address we mean bitcoin address, not a wallet". It isn't clear what "regularly" means. Some places you ask about weekly, monthly etc. Is that the same here?
Thanks, I fixed the typo and found one more.
Decentralization vs Anonymity. They are complimentary, but what is more important for modern crypto users - that is a very interesting question, actually.
The address. We try to figure it out do users change the address every time and do they understand why and how it works or just "use the wallet and don't care".
2All:Thanks for everyone!
We need more replies. Please, help!
