I know Coin Bloq, and he does great ico reviews, and he doesn't get paid for it, in fact many of those get butchered by him. I'm sorry to tell you, but if you make paid reviews, it is honest to do the right thing, and saying the you're getting paid, but it is also normal for a subscriber thinking that you are advertising a product, like a girl on the beach drinking Pepsi, this is regardless the amount of offers you receive per month.
Now, if you want to be a great content curator, you need to be unbiased, so you should stop getting paid because nobody wants to hear a promotional message, that's why we change channel when a commercial appears on tv, or we hate jingles and ryan air lotteries during a flight. We all hate commercials and advertisements!
On the other hand, you can keep reviewing and not saying it is a promotional message, nobody will believe you anyway.

At the end of the day you have two options:
a) You aim for having as many suscribers as possible and being one of the the top crypto youtubers, and you don't do commercials.
b) You become an ICO testimonial , you make more money and you have less views.
