Forex is profitable ?

There is a theory that says you become an expert after 10,000 hours doing something. If that is true, only those who remain persistent in their learning will be profitable.

I don't see why it is so difficult to make a profit from day trading. Theories or just chats will not make you any profit and experience in day trading. People can spend hours, days, weeks to talk of how it is good to make a living from day trading or investing but in reality there will be just talk. Unless you get some money and put them into work you will not see any results. Like somebody who wants to learn to drive without a car.
Get simple strategy and start using real money say 5% out of your total investment account. after several investments (profit or loss does not matter) you will figure out how to make a profit from investment.

Yes it is, but only for those who have sufficient knowledge and skills to trade.

And not one who answered this has long term profitable system shared 😅

You need knowledge and capabilities to use that knowledge effectively. You also need a sound and composed mind that can remain emotionless while trading.

Its hard to make sure the good broker as a newcomer but if we would make some research then we would be able to find out. But I think it is very important to join different brokers and observe like how to deposit and withdraw the money and what is the spreads and what is the kinds of account allowed.
