For now bitcoin is on the top most choice but that does not mean bitcoin is the only interest of people. Still People have same kind of interest on stock as well. The interest in stocks are still there in market. In fact for today's generations have more options, they have more alternatives weather they want to invest on cryptocurrency or traditional stock investment. In my belief on any market only matters time, market grows like we can take an example of bitcoin, it is increase as compare with past few year with passing time.
some people are just happy happy on keeping their funds on stocks as this market is more stable as compared to crypto. but for some, they want to explore both markets and take advantage of what it can bring to their portfolio.
but we can't deny the fact that a lot of people got their interest in crypto particularly in bitcoin because they have seen a good run on this market in the previous decade.
The cryptocurrency market is gaining more attention because of its volatility as well as its ability to generate substantial profits, but that doesn't mean it takes the stock market's share. I have a few friends who have invested in stocks and forex for a long time, but they still decided to stay with these 2 markets instead of switching to cryptocurrencies. For them, the volatility of cryptocurrencies is something they feel is not safe. Therefore, it can be said that both markets will have their loyal investors, it will not be possible for cryptocurrencies to make the stock market less attractive and vice versa.
