Well, what I meant by "what do you want to accomplish?"  was more like your trading goals in terms of money if you have them. 

For example if you're new and have 1 satoshi but huge dreams of turning that into an empire it's a different conversation than if you have a little cash but lots of experience. 

You can start with a very small amount and if you're new I suggest starting with the minimum allowed by the exchange you're on. 

Do you have a strategy yet?
