Buy BTC for cash, send them to trader, trade back for cash with trader but then i'm lost because i have no good way to get the funds on paypal again.
Maybe someone can advise me so i can go to buy BTC for cash here and there and make a profit
There is Lot Of ways in Which you can make profit on Trading:
Buy BTC when they are at Low Value Hold them for some time sell them in Fragments when there is increase in BTC price ,
Important: remember to sell them in fragments , doing so will insure you are getting an average Profit on each of your Trade and will help you in getting much profit than selling a whole BTC.
I say trading is more of a higher form of gambling despite what you think.
You cant win all the time, nor people can predict the future despite whatever TA thats provided. I say those who are trading are people who had previous experience with day trading which is overlooked by many.
