Not just full-time trading, but one should not trade at all if they have no money or if they can not afford to lose the money they are going to use. This includes borrowing money or getting loans to trade. It will massively affect one's emotional aspect of trading and that will be the beginning of a big mess.
Yes, you are absolutely right, I completely agree with you because trading is a very risky platform, there is a guarantee that you will lose money here, but there is no guarantee that you will make money. For this, you have to use such money on the trading platform that if you lose money, there is no regret. Moreover, you can never use money on a trading platform by borrowing money, if you use money on borrowing, then a person will be more in debt.
The Bitcoin market is very volatile and it is not possible to say for sure when the price will fall and when it will increase. In trading, it is difficult to have a guaranteed chance of making a profit. And the possibility of loss is higher than profit. Therefore, if someone uses the money for their basic needs to trade and loses, it will have a negative impact on their lifestyle. Therefore, one should be careful about this and of course, apart from basic expenses, one should trade with the money that we have the ability to lose. In addition, many people trade with loans, which is very risky. If such activities are lost, it increases the burden of debt, frustration and anxiety. Therefore, financial security should be given utmost importance. And one should take risks as much as one can afford.
