I just wanted to share with you all what I have noticed during the time (which is not much) that I am dual mining Eth+Zil in a pool.What I find it to be advantageous over single mining is that when the daily reward of Ethereum are higher the daily reward of Zilliqa are small but when Ethereum rewards are small which mean less money from such rewards,the rewards in Zilliqa goes extremely high.Let me give an example based on a 285 Mhsh processing power,when I was doing daily an amount of 0.0055-0.0059 Ethereum I was only doing near 8 Zilliqa but when I was doing an amount of Ethereum 0.0046-0.0048 daily due to very high difficulty I was doing like 17 Zilliqa per day and if we see for a month here is about 500 Zilliqa which can make up in the end for the amount reduced from mining Ethereum daily.I would call this an advantage for the situation nowadays.
Sorry but it is not correct. Maybe you think you get more zilliqa when the ETH reward goes down, but Zilliqa rewards depends on the difficulty and network hashrate like ETH.
Zil reward and eth reward are not related to each other.
I mine ZIL since Block 0 and the rewards fluctuate much. Some day i get 100 Zil and the next day i get 50 Zil.
