considering your mindset is still based in USD then you would be right IF this investment and diversification strategy would have been based in having an edge against︀ other market participant - this is not only difficult but extremely rare and most "investors"︁ will get what they deserve
I will borrow Warren's catchy words... the fetish of investing︂ is a rat poison and desperate last resort how to escape a certain financial death︃ - unfortunately for most people it's a net negative idea, they feed financial "experts" and︄ institutions, bring discomfort and fear to their lives, undergo huge counter party risk, waste time︅ they could use more productively using their primary skills and develop businesses, ... all that︆ for returns that hardly ever beat the official inflation, not mentioning the real one
bitcoin is not an investment, it doesn't require any expertise, consultants, time, counter party risk etc.︇ - it's an ultimate asset for conservation of capital - which is something we all︈ are actually looking for and only tiny fraction of the population should invest as their︉ primary occupation or hobby of its kind
