if you use the martingale technique make sure you have enough money,
No none has enough money.
For being successful with martingale strategy, you need unlimited balance. So, no matter how much money you have. Whatever amount of money you have, you will finally lose all that if you use martingale strategy.
Funny but you actually said the truth, martingale strategy is on way to burn money really, though a lot of gamblers don't realize this, personally, experience have thought me never to use the martingale strategy as i feel it make one lose even more.
I liken this strategy to a trader who is using 100x while trading in the futures market, this is very risky because any slight movement the price of the coin makes to the direction that is opposite from the one that you choose, the exchange will not hesitate to liquidate and terminate that position, and all the money the trader put in will be gone in a twinkle of an eye.
