Im trying to code a simple Bitcoin currency converter

the thing is I dont know how to connect to the Poloniex API using Java

I did google search but i cant find any tutorials - does anyone know some, even youtube doesnt have many

i heard the best graphic card for ethereum mining are the radeon R9 series
which 1 would be the ultimatly best of them price/profit comparisson

i was thinking off buying about 5- 8 graphiccards and connect them together for mining

i was reading from numbers between 25 -33 Mh/s pro card- is this somehow plausible?

so 6 cards would give me a total of 180mh/s

genesis mining gives you 100mh/s for 2600$ where 6 cards cost me around 1600$- of course i would need to pay electricity but i also keep the cards plus i might sell them 2 years from now.

should i go for it or is there a better way to go about this?

thanks for your help

i can mine ethereum? thats great
how much can i expect to mine per month?

can some one let me know what i can mine on this laptop?
and if this makes any sense financially

thank you
