I'm new on this forum. I mine ethereum but I read zcash is a good alternative, especially for older generation gpus. However, based on my estimations, the profitability is quite low compared to eth, and I wanted to make sure I calculated right.
I noticed most of the cards used for mining are giving 30-40 sol/s. Given that rate, considering the current network hashrate and blocktime I estimated a generated monthly mount of about 0.05 zec. That translate in about 20 usd per month, from which I should deduct the electricity costs.
The same card would generate around 150 in eth mining. I'm sure something it wrong in my formula but I dont know what:
block_reward * block_time * network_hashrate / miner_hashrate
So could you share how much you mined in which interval of time, with what hardware hashrate?
