I gamble and trade USD to BTC and vice-versa, gambling and trading can be very close sometimes if you trade randomly and will have no difference to gambling in general, but using indicators and trying to predict using news and the like can make it a little different.
I can tell my observations unequivocally, but the answer will be completely objective. The thing is that trading on the stock exchange is a job that somehow makes a profit. Sometimes this profit is big or small, depends only on the price jump for this or that currency. But gambling is such an activity that you are either lucky or not. Most likely it can be called a hobby and a very high dependence.
