I personally use a spreadsheet but I'm sure there are better way to do it.
Do you know any good websites/apps to do it?
You probably are the kond of person who wants things organized, neat and tidy. For me, i don't usually have much time arranging ledgers and spreadsheets. I seldom even look into an app i downloaded for this specific purpose. I just check real quick the history of my trades through the exchange site itself where i'm trading
Daheq? i think its just a heartache if you are keeping track of wins or losses. And honestly its just too tiresome to keep a record on it specially if with just small amounts. Because sometimes you are just aware on your winnings and losses. Especially for the big bets. But if people are comfortable with keeping track then its ok. I would keep track on my spendings on bills from the house and tuition fees i have spent but i see gambling as an entertainment only so i guess i dont bother to keep track of it.
