it is a matter of experience. you can't say which one is better than the other when it comes to trading. they both have pros and cons of their own too. for example bitcoin is more volatile while it is more profitable. but stocks are less volatile and less profitable while at the same time they have risks of dropping hard like these days.
for someone who has spend years in stocks market and traded them so he has a lot of experience: stocks
for someone who has spend a long time in bitcoin market and traded bitcoin so that he is familiar with how it works: bitcoin
for someone who has no prior trading experience and has never been in any market: neither!
There is no doubt that stock trading, like Bitcoin trading, has its advantages and disadvantages. But one should not argue that a newcomer doesn't need to trade either.
This is not the right advice. Anyone has the right to start trading any assets. The main condition is the desire to learn to trade.
Everyone chooses a more suitable market for trading, and some combine trading in the stock market and the crypto market.
You need to understand that the crypto market is more volatile and dynamic than the stock market. And this may not be suitable for some people.
Personally, I prefer to trade in the market of cryptocurrencies. Here, everything happens faster and the earnings are higher (but the losses can also be higher) than on the stock market.
In order to start trading, a person will need to learn the necessary information, get practice and develop skills. All this will take time, but if a person has a real desire to become a trader, he will cope.
