Demo trading is seen to be one of the unrealistic scene because it doesn't make any sense. Why trade with account that we wouldn't be serious or feel the pressure of the market because the funds used for trading is not real and we can be able to fund the demo account any time we feel like. I'll not slash my time to demo account, instead let me deal with the live trading where I get to see my capital, my profits and losses. Yes, the market comes with its own full alternatives and toiling our motives. Trading is not easy and we do our best to ensure we're sealing every move to adapt to the system.
Demo trading is not pointless, though. It's good for new traders who are still trying to learn how to place orders, execute take profits and losses etc. It's also good for testing out some strategies before one can go into real live trading.
So I 100% recommend it to newbies, after which they can start using small amounts to test the waters.
