Greedy players usually double down it but standing or hit one more time is the best choice here if you are playing with limited funds. You need to play the game slowly to make sure that you can secure profits with the 1mbtc free bet.
Nothing wrong with not doing hits.
Because you playing with the books, most of us will double down because have a small card for the dealer. I also are gonna to do the same things (will double down), anyone who currius about gambling strategy.
