I receive a lot of questions, and I guarantee to answer only those that require a donation. The best option is to donate Bitcoin to the address bc1q2sqhcfjzr8wph46z4gz294arg4ql4ww40wzcxs.

Other methods are listed on the donations page. When donate bitcoins for the question, please add the transaction number to the question form.

I can also write a review of an article, post, video, etc. for a donation.

Without donations, I select only the most interesting questions. I used to answer almost everything, but I’ve already covered so many topics, and I don’t want to repeat myself.
