and assume started with 0.00005 BTC (5000 satoshi) with automatic betting , every 1 second 1 bet

to lose all he got (and here is 52.4288 for example) , with Martingale technique he got 20 chance to win 50% for each
-snip-

There are few things that is off with your "calculations" that you forgot to take into account :

#1 If you actually has ~52BTC you wouldnt want a dust bet of 5000 satoshis. It is much better to play at a higher base bet and not to
use martingale at all. It is proven many times that martingale could be one of the worst strategy however a variances of it could be
used for better chance to win

#2 Roulette has an edge of ~2.7 % for single zero wheel and ~5.4 for the double zero wheel and if you actually want a 2x payout
martingale then dice would be a better option because of its lower house edge or even BlackJack for the 1% < house edge

#3 The probability to get over 20x loss streak is not actually "rare" is most cases it will happens at 0.00011637 % chance . Number is
actually close to zero however this happens quite a lot

doing it right can make you have a slight advantage over the others.

Take your time to read ( bolded in case you missed that out ). Also you should be aware of this that there are some "strategy" that actually able to "lower" the edge against you. Most people are not aware of this and just gamble it off "blindly" instead of "smartly".
Smart strategy including taking advantages of bonuses, giveaway and also some cashback . Most people are not aware of this and just gamble it blindly and hope the goddess of luck struck them some profit .

As for the "doing it right" words, thats merely not true because most people use bot to start a martingale sequences and there is nothing about "doing it right" because once you start the bot it will be based on your luck and nothing about "doing it right" because you are not manually doing it

Here is an 81 pages about martingale , mostly repeated answer and even read some of your post that you actually despise martingale https://bitcointalk.org/index.php?topic=610339.0

Yep, doing it right would make you have better chances to win:

"True. But it's better still to play a single martingale sequence than to make a single bet.

Instead of betting 2 units at 1.5x (66%) to get to 3 units, with a chance of success of 66%, try betting root(3)-1 units with a multiplier of (3 + root(3))/2, and if you lose, bet the rest at the same multiplier. If either bet wins, you'll have 3 units. Your chance of success is 66.1768%, which is higher.

The single martingale sequence has a lower expected risk, and so has a lower expected loss."

Quoted from dooglus, as you can see if you know how to do it you can have a slight advantage as i said in my previous post but it's a really small advantage
