This is a tough week for bitcoin community. Wishing speedy recovery of funds for everyone involved.

Lessons learned for the rest:

1. Hardware wallets - were always a vector of a possible attack. Just like you can't trust 100% your ISP, your PC and your phone, same goes for hardware wallet.

2. To protect yourself, always use a passphrase. It makes these kinds of exploits million times more difficult, if not impossible.

3. If you have any significant funds, you must have a passphrase. If you don't, you haven't done your homework.

4. Coldcard is the only wallet that was impacted by the seed-generation issue, you are perfectly fine if you didn't create a seed on Coldcard. Trezor, Ledger and other wallets don't share the same firmware as Coldcard.

5. I wouldn't recommend Coldcard at this point but the device itself, as far as we know, is still perfectly fine but you need to realize that company is most likely going out of business, so won't be getting much support or updates from them after this.

6. Apple, Microsoft, Meta, Oracle and other firms had bugs in their code that allowed people to steal stuff. Coinkite had a bug in the code as well that allowed a nasty exploit. Bitcoin doesn't have a bug in its code.

7. Self-custody is not for everyone. If it is easier for you to let someone else manage keys, you can/should explore those options. But companies and governments fail and it happened many times in the past as well, so nothing in life is 100% guaranteed.

Needing to set up a cold wallet. Any advice of what to be looking for?

Hello, I have an mk3 which I haven’t touched since like 5 years and would like to move my funds to a different wallet. I have created the seedphrase with dice rolls but I don’t remember how many times I rolled and I also added a passphrase. I feel like I forgot everything about how to use the coldcard. Can someone give me a guide what should I do, especially if my cc was not “touched” since the first time I moved my funds there ?

Curious how you guys here approach sending larger amounts of BTC between your own wallets. Do you split it into smaller transactions? Use a specific type of wallet for the receiving side? Double-check everything multiple times? Or just send it normally and accept the risk?

Always interested in hearing how experienced people reduce the chance of mistakes when the amount actually matters.

Many Bitcoin investors believe that the best strategy is simply to hold through every market cycle. I understand this perspective, especially because Bitcoin’s long-term adoption and scarcity are the foundation of its value proposition.

However, I’m curious how Bitcoin investors think about risk management during different market cycles.

Some holders never sell, while others take partial profits during extreme market conditions and rebuild their Bitcoin position during major corrections.

The goal is not short-term speculation, but understanding whether disciplined portfolio management can help investors stay invested while managing volatility.

How do you approach Bitcoin investing? Pure HODL, or do you adjust your position during different market cycles?

I’ve been exploring Bitcoin for a while, and it’s been a valuable learning experience for me. With patience, research, and good risk management, I’ve been able to earn from it over time.
If you’re interested in crypto, take the time to learn how Bitcoin works, use reputable platforms, and never invest more than you can afford to lose. It’s important to do your own research and avoid offers that sound too good to be true.
Has anyone else had a positive experience with Bitcoin? I’d love to hear your thoughts.
