anyway, availing those free boxes will not really give you substantial funds as your bankroll. the freebies are mainly for testing their games, you can't even use it for sportsbetting. and with their wide-ranging options of alts that you can deposit, you will not run out of options if you do really want to play using your own coins. i don't think providing another option for captcha will be their priority. just come back when the set of captchas is already easy for you
You can use it when you have a good amount of dice and slot if you want to maximize your playing time and bet you have to deposit, you have nothing to lose here because for every bet you'll gain BFG tokens that will soon be traded in BIswap.
Do we have the exact date when Bfg token will be traded in Biswap I keep looking for an update and on Biswap announcement but nothing is coming, I hope they can come up with an exact date.
