Stock market is very old and mature as compared to Bitcoin. There are huge numbers of investors/traders associated with stock market. This forum is about Bitcoin that’s why majority of people will say they will prefer Bitcoin over stock because that’s what we are familiar with. I would say it’s a personal choice to choose between both or we can develop a hybrid model in which we invest in both crypto and Bitcoin.
Stock is a tricky business because you have to perform research on different stocks before picking the few for investment. While in Bitcoin, we only have to focus on one thing i.e. Bitcoin. The advantage Bitcoin offers is that it’s safe investment if you are planning to hold it for long term and also affordable because you can invest a specific money every week or month i.e. DCA.
Bitcoin is the best coin tested with time, and to be safe and have the best stability offered yet, one should put effort only into it, and he would probably succeed in his investment.
That's why it's so important to remember what the risks are and where they are minimized for you.
