Trading is for individuals who can afford to lose money, so if you cannot afford to loose money; please do not trade. In trading we are here to multiply money and not create it; live trading helps you compound losses or multiply money; while demo trading creates money for you.
No risk, no reward; start practicing your trading strategy on a live trade; even if it is 1$; feel the heat and develop instinctively.
Yep, most people that struggle to have any sort of success in trading are either just don't know what they're doing, or they're risking too much money in trading which often results in not so good decisions when market is going against you.
In other words you could say only those who are willing to lose their money in trading or investment will make it, more often than not if you choose your trading asset/investment wisely and it went down in price short-term, it will go back up if you don't have problem with waiting.
So just set aside a part of your capital you don't care losing and use it to trade/invest in something that you are optimistic about its future and totally avoid trading anything that is not valuable in your opinion, even if it's just for a day or two.
