A very good outline from Kaspersky on the 6 challenges of blockchain and bitcoin.
Full link is below, but for the Bitcoiners in this forum have you considered the following:
Blockchain is open, and everyone sees everything. Thus, blockchain has no real anonymity. It offers pseudonymity instead. Putting aside the significant issues that crooked users have with that, here’s why pseudonymity is bad for honest users. A simple example: I am transferring a few bitcoins to my mother. Here’s what she can learn:
How much money I have at any given time.
How much I spent and, more important, what I spent it on. She could also find out what I bought, what I gambled on, and what politician I supported “anonymously.”
Alternatively, if I paid back my friend for some lemonade, I would thus let him know everything about my finances. That’s hardly a trifling matter: Would you reveal the financial history of your credit card to everyone you knew? Keep in mind that this would include not only past but also future transactions.read for yourself:
