I reccomend following based on your preferences. I do my own bets, but I use some of the famous and not so famous betters as refferences. Reddit has plenty of good betters, especially JK, Five Dragons, Squigeons and Kayari, but everything depends on your bet style.
really love Garet's bets. if he skips, i'll try Phoenix that day instead. havent bet in about a month in a half, checked Garet's page last night and was like yes, lets do it.
since i've been following i've went with JK, which has been pretty consistently good for me. last 2 days were bust, but that happened to almost everyone today so i'll stick with them unless it keeps happening.
