Cryptocurrency trading is similar to trading the stock market, but in this case it is not about goods or services, but cryptoassets. In any case, it involves its risks and should never be done if we are not prepared, plus, as you say, we should only use capital that we are willing to lose, otherwise it is irresponsible, as the market is extremely volatile and from my point of view, it is stressful,

For those who take it seriously, it is a science, for others, it is simply a gamble.

Best of luck.
