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
if we talk about return from that market, in my opinion cryptocurrency give bigger earning than stockmarket.but you should know the risk involved bigger too.
If you talk about risk then bitcoin would be one where you can lose your money where stock market are not much risky since they're exist and there's a company behind it.
