still don't understand how to get profit, sorry im noobie (newbie)
What do you mean? it's very simple mathematic calculation.
Profit = (Your current amount - your initial amount)
Profit = $3000-$2500=
$500
%Profit = (Your profit / Your initial amount)*100%
%Profit = ($500/$2500)*100%=
20% profit
OP, what the heck with 1.15% increase?
