I will choose both. Because both are different from another. The tools used in trading in stock market is similar to crypto, but then they are both different asset. Stock market may be stable, while crypto is starting, I believe crypto is the future.
In terms of trading, I would like cryptocurrency more because of its volatility and I need a little amount to trade whereas in stock market, it is somewhat stable so I would need a bigger amount in order to have massive profit from it. It may be better to trade in stocks if you are conservative with what you are trading because at least it is legal and backed by government and cryptocurrency is not backed by government yet. I would like to invest in both though because I would like to diversify my investments.
