hey im have 16mil in cash and was wondering what would be the best thing to do with it either to make more or to use on skills but still make or break even on them so i don't lose it all average lvl is about 65-75 in non combat stats and 98 combat plz give me some advice

make yew long bows with fletch, u usually break even or sometimes even gain a profit if im correct, and with 16m u can get 99 fletch easy
