places have already begun to appear on the planet where cryptocurrency is full-fledged money, so the answer is definitely yes, but if you had a life on the profit from speculating in cryptocurrencies, then everything is a little more difficult to make money on investing than to get into the 1% of selected traders who consistently earn on market volatility

Arguably, I could say politics. At least the sort of politics that I see going on in my country, where you've got politicians assign projects to themselves and friends, loot the treasury and don't get questioned for it. Another of such is the foreign exchange market (FX) but I guess currency market goes for that.

Again, in general, trading have got some good chances to enriching an experienced trader but make no mistake, it goes both ways.as it could take from you not just your money but, can as well affect your mental health.
It becomes a thing of great importance that you put good effort in studying what trading entails, practice wth fake money and could try the real trading little by little with small funds.

You are absolutely right cryptocurrencies are a paradise for traders, You will not find such huge profits anywhere except the cryptocurrency market, but for this you need to have free will from other people's influences, your decisions should be 100% yours and not imposed on you from outside. Not many people can do it.
