your trading capital is just numbers on the screen, the method and ways by which you manage those numbers is what will determine and make you a good and profitable trader.
ITS GOOD TO KNOW THAT ANYONE CAN BE A GOOD TRADER WHEN THEY ONLY SHOW YOU THE PROFITS THEY MAKE. DONT LET ANYONE RUSH YOU INTO WHAT YOU ARE NOT PREPARED FOR
This is a good advice and anyone who listens will mostly make a good trader. Just like you rightly said, trading is not child's play because at every point funds is involved which will either be lost or gained more and the only way to gain more is by sitting down to learn. Most people today that complains about trading are likely those who jumped into it without enough knowledge. Therefore my suggestion is still same as yours, which is, anyone who really want to trade and make the best out of it should first and foremost learn about trading.
