I don't think it's necessary to attend conferences just to have an idea or knowledge about Bitcoin. It's just a second option, in my opinion. There are many ways we can learn to understand Bitcoin. I have been in this field for several years, and I have never once attended any bitcoin conferences.

Because this is not practical in my opinion, for those who just want to attend, there is no problem. We can learn self-study, and most people here in the forum know that. But I agree with DCA because it is a really effective way to save Bitcoin or crypto.
