we have nothing called "exchanger" and as others mentioned you need to explain what you mean by it, it is not a real word.
also if you want to choose trading as a profession i think it is possible but you have to accept two main things
1) high stress
2) lots of risks.
when you trade as a job, like what day traders do, you need to invest a lot of money into this and do it every day and have your eyes open with a lot of bots and alerts on 24/7 and that is not easy, that is time consuming. but also it can be very profitable.
also when you invest a small amount like $100, that means worst case scenario you lose $99 and get out before the $1 is also lost
but when you invest something like $10,000 then a small loss where you didn't care like a -10% drop means losing $1000 in a flash. and that is the high risk part.
