No, when I invested 100k₹ in my brother's shop, it was able to turn a profit in a few years and pay me back with interest. The money came from selling products and generating revenue. With Bitcoin there is no revenue. The only way you can turn a profit is if you get some other greater fool to buy it from you. This is how most ponzi schemes work. I find it very scary that the people investing in crypto don't even understand the basics of investment. They genuinely think that all investment follows ponzinomics.
