Well, appeal to authority doesn't quite work in this case given that I was a principal engineer at one of those big tech companies :P. People that were pro blockchain were generally not treated favorably because we all know it's utter BS.

I agree if by "blockchain technology" you mean the broader semiconductor industry. Blockchain itself has found no meaningful application where traditional database tech wouldn't service faster and more efficiently over the course of its existence. Invest in the industries that make beanie baby manufacturing possible, but not the beanie babies themselves.

Let's be honest 5% is a massive exposure for a portfolio at any scale. How about 0%.
