Yes, stocks aren't volatile as bitcoin and that's why bitcoin isn't for the fainted heart. While for stocks, it's good as the game of the whales too but not that much volatile.
The volatility of stocks may not be comparable to the volatility of bitcoin because the price of bitcoin is known for its high volatility. Both of these investments are risky but the risk of investing in stocks is arguably lower than investing in bitcoin. To be honest, I didn't know much about stock investing until I read a few things about it, but I truly believe that bitcoin investing is much more stressful than any investment.
When you think that you're not yet fine in diversifying in some altcoins and other investments aside from bitcoin/crypto, you can have your own journey in picking stocks. Honestly, it's one of my plans but I haven't executed yet since it's going to require me another capital that I'll allocate there but hopefully, someday if some of my investments goes on high again that includes bitcoin, I'll diversify on a few stocks.
Having a little capital in stocks will only teach you some lessons but it won't grow as much as holding bitcoin. For which, has been proven to be one of the best assets that really changes one's lifetime based on how long he's holding and at what price it has been bought/sold.
I don't know exactly which assumption is correct, but I think these two investments are also profitable in the long term so they are also worth considering. But if you ask which one is the best, I'm more likely to choose bitcoin that I have known so far over stocks.
Just like in crypto, your picking of stocks will also be crucial. We may say that in general, it's profitable and the same goes for investing in crypto in general. But there will be stocks that won't be profitable even in the long run because of poor business management of that company.
