That's a waste if they learn and understand btc but they do not have a money to put on it while on the other hand there are people that do not understand btc but then takes a risk and then lose. I think that if a person is willing they will do anything even if its hard just to get what their hearts desire.
Your statement is so daft. There is no knowledge that's a waste.
You must have heard of Gold back then but you choose not to invest, does that make your knowledge a waste?
What do you say about Warren Bufet, they are aware of it flaws but didn't give it a try because it was never something they want to put their money into.
I was introduced to bond when I was in junior school when we attended a inter school competition, despite the knowledge and encouragement, I never dreamed of it and I was even aware if bitcoin then. It's a choice to have knowledge and to also make used of it.

In summary, acquiring knowledge is one thing and investment on it is another thing.
