A friend of mine just got into Bitcoin, lucky for him, his successful. Before he started Bitcoin, he was actually into a good business of selling artwork which wasn't so bad. So he got introduced to Bitcoin and had a quick success. It's actually a good and exciting thing to see someone progress fast like that, but he quit selling artworks and other little businesses that kept him going he stopped, he now depends fully on Bitcoin. Bitcoin is the king no doubt, but From my Point of view I think that depending fully on it might be risky to you financially. I don't recommend anyone to depend solely on Bitcoin or any single asset. Bitcoin can fluctuate rapidly and market volatility might impact your financial stability. It is actually very risky to invest in a single asset. The part that scares me the most is that my friend has put all his resources into this one asset. If am wrong please correct me. Thanks
Op your concern towards your friend is so real and amazing, many folks fails to understand that putting all your eggs in a single basket is like exposing yourself to a more higher financial threat.
It very crazy to believe that anyone will quite is business or well paying job just because he or she invested in bitcoin not knowing that this is the major strength of that investment, your business or job can serve as a daily or monthly source of income that will be use to fund (buy more stash of bitcoin) your investment to any hight that you want, and can also serve as a sustainable funds that can sort all your bills through the years of your investment.
however, my little advise for all investors, what ever side hustle you find your self doing, do it with every strength in you because if anything eventually happens to it your investment could be a nightmare because you will definitely start selling it at lost to sort out your problem.
