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
Definitely Bitcoin is not an asset you would rely solely on without having any other investments because it's basically for long term and fluctuating prices can lead to losses in most cases and having it being your only source of income can be very risky as you lose everything.
So it's best preferable to have a physical business to look after and monitor your profits because it's within your control and settle necessary expenses and subsequently investing in Bitcoin from little profits.
