There's been a lot of advantags in crypto trading for a new user. Crypto trading have got lower amount risks than gambling & forex. Where in gambling & forex you always have a chance that your fund can be zero. But in crypto trading you can get notifications from exchanges if any of your purchased token or coin going to be delisted. There's always a chance for you to recover your fund.
I do not quite understand the meaning of the highlighted text.
In reality, forex and cryptocurrency trading are both forms of gambling, and the risks all depends on how you trade and what strategy you adopt.
Also on the measures you put in place, like stop loss and take profit to protect your profits or minimize your losses.
In all three there's a chance of your going to zero.
