That's exactly why few people wrote here that hash rate race is not good if no explicit reasons for that since it does not increase profit but decreases it due to power bills. No one listened, now it is the result: more power, more expensive PSU setup, etc. And not more profit :-)

Don't mix a warm with a soft (mining with shopping). When ETH dual miner was created, Claymore changed its default intensity from 16 to 8 to save few ms only. These ms cost some stale shares since after share is calculated, it should be delivered in time. Using -i 16 created larger jobs from CPU to GPU which can't be stopped until finished, and even those ms were important. Now we talk about Zcash, it has slower block time, but solutions itself are huge comparing to ETH ones (around 1300 bytes vs 50 for ETH), and all this now is encrypted in addition. So you have exactly the same case, but for some reason no one is concerned with it like it was for ETH.

Someone tells no one will see their addresses via SSL. If you are paranoid, you should not use exchange addresses. Install zcashd, mine to t-addr and move all to z-addr, send to an exchange t-addr, and no one will know who you are. No one except you will even know from what z-address funds came to the exchange. This is what Zcash was created for. You do not need SSL for that at all. Use right tools for particular task. I understand that 90% people here are home miners, they never read about Zcash: what is it and how it works. Still, it provides 100% security if you are paranoid and use it right. Without any encryption or closed source. That is the brilliant part of Zcash that is undervalued yet.
