I would say it's not necessary, professional investment advisors don't know your specific interest of investment and they maybe an old school investor who don't know the real potential of crypto investors so I suggest do your research on your own instead of giving the decision making to someone else because you only know what you want and how much your risk tolerance than anyone else.
They are pro, so why not? And who says we will pick randomly? No, but we must only pick those who have the same field as us, so that we are sure that they know what they are talking about. And just because some of them are old, does it also means that they are now weak when it comes to these things? Nah, I wouldn't judge them too early yet.
We have old people who are also involved in crypto and in fact, many of them are better than us because they invest on it early and until now they still have their coins. We still can try on our own first and if we think we are doing well, then that's right that there is no need for their help anymore.
I can't say anyone as professional crypto investment advisor because literally there is no, most of them just pretending to be via social media and some got lucky due to the early investment just paid off and they are using it as an opportunity to monetize anything that comes in the way. I would respect the decision from a seasoned traditional investors than random guy from online. I'm just saying I am not going to take risk because of someone especially when it comes to crypto.
