Hahaha.
I don't mean to overstep my place, I just get a little "overhelpful" sometimes.
Anyhow.
My two big things that would be great to see are:
1. You already addressed it, but stopping all the antivirus software from needlessly blocking mining access.
2. Mining other cryptonote coins. There's already somebody else doing that here:
https://bitcointalksearch.org/topic/tomosmining-highest-paid-mining-btc-faucethub-5-ref-2527462 but he has no infrastructure for publishers like you do. But by switching the mining effort to coins like Electroneum, or such, as the mining profitability changes, he gets about 300 satoshis / million hashes, which is much better than plain coinhive.
Number two is likely pretty hard to do, and would likely take a lot of infrastructure work, but if you could pull it off, I think you'd probably overtake coinhive.
Even if that turns out to be something y'all don't want to do, you're still (in my opinion) currently the best game in town. Your withdrawal minimums are tied with coinhive. But. If I withdraw at .02 XMR on coinhive, I'd lose 25% of that in transaction fees, plus I'd have to send from an exchange to my faucethub, losing even more.
So I'm content.
1. Yes, this was already mentioned.
2. Yes, we are looking into it of course, cause this can make us much more competitive due to higher payouts (we already ahve higher payouts, but we could offer more). We are testing different solutions, but still don't satisfied about anything... Actually our current proxy is not perfect too and we are working on the solutions. Hope we wouldn't have to write our own proxy...
If I withdraw at .02 XMR on coinhive, I'd lose 25% of that in transaction fees, plus I'd have to send from an exchange to my faucethub, losing even more.
Glad you understand this. We think this is out key benefit. But seems not everyone understand this so far. People like unsubstantiated numbers and promises of gold mountains...
Just patience.
