Yeah it's a tough call, I've just stuck to one website: bitwine, not the most reliable one ..lol but not really in the space to create new accounts on other sites for some reason!
I went on a binge awhile back, like for a week or two, and started narrowing down the readers, most of them were recommended frequently in this forum, then I just gave the reader a chance or two, some no chances if they don't resonate, some I X out of chat because I knew they were not real, and eventually I've narrowed it down to 1..maybe 2 now.
So I think it may take some time to see who connects with you, and the reason I keep posting about someone working for me and not working for me (both actually), is because I want other members on the forum to see one reader may work for someone else but it didn't for me. It'll be a judgment call you make! Don't take the ones that say "predictions came true or didnt come true" too seriously because, really we are just posting to gather some data here
