I believe Coin Hi low game on freebitcoin is rigged as I have lost a steak of 12 games in a row. I bet on Hi each time while doubling my bet and lost all of my balance. What are odds to get 11 Lo in a row with 50% probablity?
if you use the martingale technique make sure you have enough money, I used to play HI and LO there but now I'm more interested in sports betting, after all their game is quite fair maybe you need another strategy to play it
Of course, because the martingale strategy requires quite a lot of money to be able to generate even larger amounts of profit.
For those who only have small amounts of money, I think it will be difficult to use the martingale strategy because in each round the bet amount will be added or increased gradually until you really win the game with the desired profit.
I usually use this strategy when playing roulette and it has proven successful.
Martingale is not good for neither for people who have a lot of money nor people who have very little. If you have very little amount of money than on your 4-5th loss you will be out of money and can't martingale even further, if you have a lot of money you could go as far as 10th bet or maybe even more but then you will stop because you will be out of money too.
This is why it's quite important to remember that a thousand dollars losing 20 times in a row is a billion dollars, see how much it grew quickly? Start with 1 dollar if you want, losing 20 times in a row is a possibility, rarer than most but still there, and even with 1 dollars it becomes 1 million dollars for that bet. I would say don't do it.
