Everything need a proccess, you won't ever get big profit although you spend a lot of money be it through trading or investing.

You'll have to learn first and I think $50 is big amount to start trading as long as you have more patient. Just traded it, if you have more about trading maybe you'll get $1 perday and it is a big amount too and you can collect it.

Regardless the coin that should you choose I think you have a right decision. Bitcoin is promissing place to be traded, just take become day trader so as you have more chance to increase your profit.
