You should understand where he is coming from, I mean it's old and traditional bankers and so they don't like Bitcoin or any other crypto for that matter. And most of them might have regret their decision.
Or others seeing the potential, could quietly buying and stacking Bitcoin since 2018 and most likely they are into profits already.
That is the beauty with Bitcoin investment though, you can buy it yourself without anyone noticing unless you tell them that you are into it.
Many cases happen like this. Even when they already know about Bitcoin, they still ignore it and don't want to acknowledge Bitcoin, and don't like it anymore. And this has happened very often, especially with bankers. It's just that, it will also be related to the mindset, the openness of the mindset to new and developed things. Bitcoin may be something new for them and they think it will damage the banking system. It's just that, they don't think earlier that Bitcoin can actually be more than banks, and the profits can be that good. And for those who understand or are open-minded later, they must have a sense of regret why they didn't enter Bitcoin earlier so they could get such big profits today.
