Car Racing - Solid. With the ".io" extension I consider it low thousands (car, high value keyword)
Coal Mine - Again, solid. A site dedicated to the coal industry, coal mines for sale / news in the sector ...abundance of uses (coinmine.co fetched $2,588) ...in this case it is ".io" ...my range is high hundreds / low thousands
Betting.Industries - Juicy. The juicy is "betting", in terms of keywords. The word "industries" I will say doesn't fit so well for me, it would be "industry" ...plus, more commonly known as the "gambling industry", than "betting". However, my impression is to not be too hard on it, looks juicy ...as a hat trick I want to say low thousands, but not totally thrilled. Again, "betting" is the big word ..."industries" I don't consider proper in this case
