Investment in bitcoin can makes you developed reasoning on how to expand your income,
does it? Actually, before someone thinks of investing in Bitcoin, they are already thinking of possible ways to expand their income or financial status. So I think you are wrong about that.
Although if someone invests in Bitcoin and is able to make a huge profit during the bull market, they could use their profit to do other things, or could split their investment profit after then and still have some Bitcoin and other investments. The profit they made from their Bitcoin investment makes it possible for them to do so and archive other things, but not really that they began to think about how to expand their income before they went to invest.
