First I got to say, they catch alot of things right away. Almost any time you try and mine anything they will usually catch it within 4 or 6 hours. I also have tried to mine many different crypto with different methods as well, so I know first hand. And have only gotten sia and storj to work without them catching it. This is what I love about "mining in a web browser".
It uses the traditional port 80 and 81 for web traffic, and also is not on there "blacklist", because you are not using any traditional method or mining program. I know the hash rate is not as high, but I have already received money.
And this is extra and free server time. I am mining with 4 instances, each 8 core 2.2ghz Xeon's with 8gb ram. This is a screenshot of just one instance, they are all identical.
And I have had the load at %80 for over a day now, I took this screenshot last night for you guys.
And here is one from this morning, from a different instance, so you can see its been smooth all around!
Of course the price is high, but free is free after all, and they are very generous with there $300 free credits as well!
