There are easy ways to check out earnings though without doing all of that.
All the altcoins are falling today
Denarius -20%
Signatum -25%
Ethereum -8%
zcash -6%
With the volatile markets we have now it's hard to calculate future profit. I think people are selling altcoins and place in bitcoin to get free "bitcoin cash" coins after the hard fork. (1st august).
Then they will probobly move the coins into altcoins again sometime next week.
Currently the bitcoin cash futures are trading at 0.13BTC
https://coinmarketcap.com/currencies/bitcoin-cash/You might get a 13% ( ?) bonus if you hold bitcoin on the fork 1st of august..
But some exchanges / wallets doesn't support bitcoincash..
