I'm not ready to post more hard numbers yet.
I think 2018 will have the greatest income than last year, even the btc today was not good as in the 2017.
No, I think that gross income will be roughly halved: the two main factors for this are my ban on ICO forum ads and a general reduction in traffic after the bubble popped (as has happened after previous bubbles). While non-ad user payments have become somewhat significant (whereas they were barely worth mentioning in 2017), keep in mind that both evil fees and copper member fees are (intentionally) tiny.
(There's no need to be concerned about this whatsoever, BTW. The forum's purpose is not to make money, there are plenty of reserves, and it would be easy to increase income if necessary.)
