It depends on what your aim is. If you want to gain knowledge or learn more about blockchain or any projects being discussed in a certain event, you should obviously do it because such seminars and events can teach you a lot of things and you can learn a lot about blockchain technology, new projects, investment opportunities, you can also meet new people and share knowledge and might make some friends as well.

So I think there is nothing wrong with attending such events if you have got an invite or a pass to go and spend some time there. If I talk about myself, I would obviously never lose the chance of attending an event where blockchain and cryptocurrencies are going to be discussed, new projects might be announced, etc.
