Upon searching there are lots of them. I'm pretty sure they can help in deciding who to put our money on, can you suggest some of them?
I think all sites that give pre-game predictions, speculations, and analysis you will see while searching are all good. As long as they provide some explanations for why the prediction turned out like that, that's already good. You have no choice after all but to believe in those predictions that you will encounter since you don't even understand the part of their analysis as you are not familiar with it.
Try to make a test. Risk some money and feel the actual betting on those sports you want to try. Nothing beats the real user experience compared to just reading suggestions.
A very dubious assumption - most of these sites are traffic generating channels. They give some kind of "analytics" and in fact they only retell the news just so that bettors would be interested in reading them, but if you pay attention, from time to time they give advertising posts about "super reliable and good bookmaker" or about "paid channel with super reliable forecasts". Such advertising is the main reason for the existence of such sites.
When we are in the betting world, we always try to research and look for the best information, but it is difficult to find, usually we always go to social networks, which can be checked on twitter, instagram, among others, but there is a Except, there are forums that are very hidden, that talk about all sports, there are even crypto forums that have their sports part and are very useful, sometimes they help because more experiences are known and what some users think, in itself, a forum always requires being more specific, on some occasions I have found very good information in personal blogs of people who are fans.
