I've been using it for the last three days, it's probably the most comprehensive calculator I have used, it made me discover at least one good coin

I'm not sure the two profit calculation are necessary.
2. the calculator considers the last price of the transaction, which was on the coin on this exchange. On some exchanges, the price is overstated tenfold. To do this, I'm in the calculator and show the volumes from the exchanges. Soon we will add a function to calculate the price of max bid
I think you should also check the
volume of the highest bid, otherwise it's too easy to throw off the calculator with a fake bid worth 0.000000001 BTC
