I am happy to give you an interview or provide you with a consultation.
I am very interested in innovative ways to secure property and personal interactions: all the way from cryptography to user interfaces. I am not interested in trading, mining or building exchanges.

Advice about Bitcoin

In a nutshell, this is what I tell people when they ask me if they should buy some bitcoins:

  1. Bitcoin is a huge thing that can transform many things in society.
  2. No one knows what will actually happen, there were no historical precedents.
  3. Do not put more money than you can afford to lose tomorrow. Do not borrow anything, do not put more than 50% of your savings, do not touch money you already have made plans for. It’s tempting, but just don’t.
  4. Before putting in more than $100, learn about Bitcoin, how it works, why it works, its weaknesses, popular myths, how past problems were solved etc.
  5. Be aware of viruses, lost passwords, lost backups, bugs, human mistakes, panics on exchanges, DoS attacks etc.
  6. Check and double-check and triple-check before doing anything. Play with small sums when trying a piece of software, or a service. Then wait a week and play with a bigger amount if nothing is lost or broken.
  7. Never blame anybody except yourself.
  8. You most probably will be disappointed at some point in time. You will be scammed, your money will be stolen or lost. Prepare for it.
  9. Never trust anyone (including me). No person has authority in Bitcoin. Even core developers are more like explorers as they didn’t write the original code and did not make a lot of decisions. And Satoshi has disappeared a long time ago.

I cannot stress it enough: even if Bitcoin becomes huge, you may still lose everything for many reasons. Be careful.

It’s a great journey ahead of us, but it’s bumpy. Don’t dive in without proper training.
