Even though I agree that there are likely advantages to learn from people with more experience, we still need to be careful in regards to both understanding the source of our information and also to make sure that we are coordinating the information that we learn with our own experiences and knowledge of our own situation in order that we attempt to make the right decisions for ourself.
And, if we have doubts about what to do there are ways to hedge our risk with position size.. that we can adjust in accordance with our learning.
A lot of our learning should relate to knowing ourself and figuring out our own cashflow situation, but of course there are other areas of learning too, such as the ones that I listed in my 9 areas to consider and to build. I am a bit bothered by the idea of "professional economist" - whether you are referring to some kind of a consultant who knows about investing, but many of the folks that we understand to be current professional portfolio advisors do not tend to advise about bitcoin because there is hardly no way that they can charge fees with bitcoin, even though in the future, there are more and more products that allow them to take a fee.. whether the bitcoin spot ETF that is likely to be approved and maybe some other bitcoin related product that might be available, but still there are a lot of disadvantages to holding those kinds of products as compared with directly holding bitcoin.
I doubt any of those kinds of biases are going to go away when it comes to consulting with professional investment advisors, even though surely there may be some of them who are able to still help you without directing you towards products in which they get a cut.
When I first got into bitcoin in late 2013, I was not really sure about a 1-2 year investment into bitcoin minimum.. but with the passage of time, it seems that the investment case for bitcoin in the long term is even greater, so I doubt that 3-4 years is a long term investment, and if you are planning on cashing out for "sweet gains," then you are surely only thinking in terms of short-term dollar gains rather than planning for a possible lifetime in which you might always own bitcoin absent some kind of notice that you might not be living very long and then decide to cash out more of your bitcoin within that kind of a context.
Sure one of the problems with older people who might be 65 years or beyond, they might start to feel that they are not really able to sacrifice a lot of liquidity, so they might be worried about their abilities to invest in the long term, and surely a person who is younger with health conditions might have similar difficulties in terms of his/her investment time horizon. No one can tell you what is your investment time horizon, or what you believe might be a better investment than bitcoin to put your "sweet gains" rather than merely letting your bitcoin investment ride and letting the gains roll over into the potential of more gains when your BTC investment compounds and compounds and compounds.. and yeah, there are no guarantees, and probably the lack of guarantees causes you to feel that there might be some advantage to realize your supposed "sweet gains" rather than merely allowing them to roll over until you reach a higher stage of actually knowing what might be the reason that many longer term bitcoin holders have way more wealth related options as compared to those who are not able to hold through even a whole cycle.
