I personally boycoitt any betsoft implenting site. Their bj wouldn't be any different than their other games which are definitely rigged. Do note that Blackjack can also be rigged despite being provably fair.
Provably fair is to the players, some gambling websites can manipulate the result, there were so many such scam sites since 2013, some sites stole the house fund, they claimed hacker did it. But actually it is the site owner did it.
