trading may look difficult to some people and look easy to some people too, many people out there are making money by trading in the crypto market, stocks market and so on, but that doesn't mean that trading is a bitter life and expensive life, people who are trading and making profits from the trading are just living a normal life like you and me. So don't let anybody deceive you by brain washing you that trading is a better life and expensive life. See let me tell you something trading is very risky, if you don't analysis the market very well before placing a trade all your funds will be gone in a Twinkle of an eye, so be wise in this crypto space.
Whether someone will live a simple or luxurious life after becoming a trader depends on how they do it and how much profit they make. The amount of profit one can make from trading will depend on two things: how good they are as a trader, and how much capital they have. A profit of 5% a day with a $10,000 capital is $500, whereas 5% of $500 is only $25. So, considering how much money one has to start their trading journey, and whether they can stay profitable in it, one can live a luxurious life as well, especially if they live in a country where the value of USD is very high and the money they earn from the market might convert to a lot of money in their local currency.
I live in a third-world country, so even if I make $100 a day, I can live a very luxurious life, and can afford anything, but if someone lives in a first-world or developed country, such as the US, it might be considered a below-average income because if one full meal costs barely $5 in my country, it costs more than $20 there, roughly.
So, it all depends on how good you are at trading, how much your capital is, and where you live.

What can give someone a luxurious experience in one region might not be enough for one to survive in another.
Yes, it all matters about on how profitable you would be at the time that you would be doing up trades. This isnt something a skill that you would be able to learn up so easily and to know that there are tons of traders who do failed up into such stuff on which they are that thriving on day to day just to acquire up that such profitability. This isnt something a skill that you can be able to learn in a short period of time and once you dont have that good grasps into it then it would basically means that you do have that potentially be able to make your financial condition or status to be completely changed up. Why? On the time that you do know on how to go with the flow with this market when it comes to its movement or simply with volatility, then you do have that chance on achieving out such success. Majority of us do wants to acquire up such skills but just been said that it would be depending or basing up with different factors. Important thing on here is that you wont be needing up for you to become perfect because there's no one would be perfect on making up those good trades from time to time because there would be always those mistakes and errors because we cant just that be able to predict with this market. It all matter about on how you would be able to sustain and be able to control up such condition, because as an individual who doesnt have that good control towards it then you would be having that kind of fear on which it will be causing up that hindrance or hesitance.
