The winners of bitcoin price for July 2021 is average $40,001 - $42,500, who the winners for this event should get 15x. I regretted to didn't bet that much, I put on much average of $25,001 - $30,000.
So, in August is it still that average? the bet already opened. maybe higher than July, possibly very close that that price $42,501 - $45,000, $45,001 - $47,500 or back to $35,001 - $40,000. maybe better to all in before closing the events (1-6 days left).
I don't receive any email from freebitco except wof. just ignored and don't click that link register, that must be suspicious like your guess.
I've hover to those hyperlinks, it seems to be safe. Both of them are referring to binance official site
Look like a spammer trying to get referral
