Simple answer is yes, if you have the means, maybe you live in an area where such events are being organized, or you are a Billionaire and can easily afford to travel out of your country for other countries where such an event are being held, it's worth it to be honest, as you not just get to meet new people of like minds, you learn new things, as well as make new connections as well, several blockchain projects became really successfully only after the founder made connections with industry experts and people of affluence through blockchain meetups and seminars and all.

So for me, it's worth if, like I said, you have the means to attend without financially straining yourself or business.
