Anyway, not that long explanation about why everyone is going to choose BTC here, you're in a bitcoin forum and this is much the preference of the majority here. But I think even if you ask this on a stocks forum, there will be folks choosing BTC over their stocks preference.
To put it bluntly, the reason we chose bitcoin is because we believe it offers higher returns than stocks. Profit is the main reason, other reasons like decentralization and privacy are just secondary to make the explanation more vivid, nothing more.
If stock investors decide to move to bitcoin instead of stocks, they will join the bitcoin forum, not the stock forum. Like you are a bitcoin investor, are you active on any stock forums? I guess not. So if you ask this question on a stock forum, they won't even care.
