If you can't see the difference between showing an ad and mining bitcoin using your visitors' computers without their knowledge, you deserved to lose half your visitors.
Who said it was without their knowledge? It was clearly stated in my TOS and I even sent a newsletter about it.
Also I had a (sort of) premium plan that allowed to pay a small fee (2€/month to remove the ads and get some extra featues. When I made the BTC mining experiment they still had the option to choose between the free plan (BTC mining) or paying 2€ to get it removed.
