Don't trade because you have such money already available, trade because you trust your trading skills and strategies and have backtest it to have worked many times in live trades. Trading isn't as easy as some social media platforms makes it sound. Do your research!
Most traders lose money in the market rather than getting more money as profit so if you don't consider yourself as a good trader and are able to get profit in long term (remember what means is long term profit, not short term profit), you should never trade.
Moreover, belief or confidence is not enough and you must be confident about your trading capability only if you base on your trading record and as emphasized, long term trading record. If your record shows that you did not get profit in long term and only get loss, don't try trading.
Of course people lose that much because trading isn't as rosy as some of us are told. There are some basic necessary trading algorithms you have to consider as a trader before jumping on taking any trading position. Some so-called traders can really read the candles to decipher or identify certain support or resistance levels to be able to predict what direction the market movement might take to in order to know where they can place their stop loss and take profit
