I've attended just one where I saw Vitalik Buterin and it was a great experience. Though I encountered that he spoke more about his smart contracts and Ethereum instead of talking about Bitcoin and the Blockchain technology. It was my bad as I am not good at technical part and that's what was discussed mostly. CES was missed by me and I have been watching videos uploaded by users who gathered there, such an innovative event with the world's leading tech giants representing their skills through their works.
Hey, seeing him in real life is really cool especially if you had a chance to talk to him personally for networking. For me, I used to go to blockchain meetups very frequently and then I gave it a break for personal reasons. Since September 2019, I started to join blockchain events once again. So far it's going well, but the sector was suffering from the negative market conditions a bit as you all know. Yet I see speakers and blockchain company representatives are being positive again for the further development, which is very promising for me. Can't wait for the good ones to participate this year, I've been following the calendars all around.
