I've been following a couple of threads by
BitcoinSupremo. They seem to have some good tips, and what I have seen so far has been free. You might as well give a look and see.
just visited her/his thread, and seems like she/he only pick a favorite teams and low odds above 1.50 overall which i think it's not a tipster at all.
i would recommend more experienced tipster like joca97 , he is a professional footballer too , more reliable i guess.
Joca97 offer free tips? Wrong, only premium..you can visit his topic and there is no free picks, he offer just premium and price is to high and odds are low...maybe he has a lot of experience but he is not my choice.
Take a look on coinviser, they offer everyday free tips and also premium tips, you can choose the odd that you wanna to bet, and not just like joca97 with avg odd 1.40
because joca97 have an outstanding record with his previous free picks in the past he decide to post free picks only once a week not everyday.
it's reasonable, if you only follow the great free picks maybe his premium picks would never sold/used.
no doubt i recommend joca97 rather than any other for now.
