I tested this calc. Very interested, but need some bug fixes and add some features. Some coins have not correct calculating. but generally interesting.
Thanks for the feedback. Here is some explanation:
1. I physically do not have time to view the correct reward for the block for all 1200 coins
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
3. for some coins at a small volume prices are VERY high. but not one exchange us the glass of prices is not transmitting
BUT if you substitute these coins (complexity, reward for the block, the price at which the calculations were made), You will get the same result that my calculator shows
so if you choose a coin for mining from my calculator, then you need to check: the reward for the block, and at least a glass of prices on the exchange!!!
