Trading is also dangerous but there's a system to it that makes it profitable than gambling. The problem why a lot of traders end up losing is because they don't follow the rules. When trading the financial market it's important to always remember that it's a step by step process. Trying to make money fast is going to make you lose money rapidly. But like you said it's best to stop when you are losing consistently
Newbies do not even know the rules, or how they should trade, so giving up at early stages without knowing what they are doing or they should be doing would be a bad idea. I disagree with OP and he is making a big deal out of trading like it's something some people can do and some people can't do. This is why it's not that easy to make some returns for the benefit at the moment.
I can't really see a way that newbies should give up without trying more it's obvious that we are not going to get the results that we desire, and because of that it would make more sense if we could just make a lot of return with the market that we already have by trying to learn more and grinding until we are good, even if with small amounts.
