The minimum bet amount you must choose is equal to no more than 1/2000 of your Bank. Why 1/2000? Because you will have a margin of 9 losses of the generated number in the range you selected and the balance balance for the 10th bet, after which there is about half of the balance. Again, from experience, I will say that for more than six months of participation in the project, I have met a series with more than 10 losses several times, and in 8-9 losses-on average 5-6 times a day. In most cases, the losing streak is 2-6 times.

Therefore, for maximum confidence, use a bet of 1/2000 of the balance, as this is a guarantee of security and the ability to start replenishing your balance again using multiple BTC without waiting for the balance to increase to the minimum recommended for the game, which takes you 1-2 days.

Taking into account the recommendation regarding the balance size of 5000 Satoshi, the maximum bet is 3 Satoshi. To earn at least 200 Satoshi (these are the blocks, for convenience, I will call them so, I recommend playing first until you understand the whole procedure and evaluate all the possibilities, after which you will increase your minimum block), you need to get into the specified range 70 times. 70 hits — is it a lot or a little? About 6-7 minutes if all recommendations are followed and the strategy actions are clearly implemented.

Here I will describe the possible income on the example of my history. I omit the time of my experiments and zeroing the balance (you should not have them when performing strategy actions) and consider only the period of increasing the amount starting from the zero balance. For convenience, I'm not tied to days, but to hours, as a unit of balance change. To determine the number of days, the number of hours is divided by your possible attempts during the day (each of them is different, for example, I can perform 16-17 entries of captcha and games in multiple per day).

The table shows that to achieve a balance of 43020097 Satoshi, you need 250 attempts to play. If you perform 10 such attempts per day, then you can get this income for 25 days after the start of the game, while spending up to 1 minute per hour or one and a half hours per day. In addition, it does not take into account the input of captcha and possible income from referrals. In fact, continuing to play, thanks to the progression, you can reach larger amounts of income, but do not forget about the withdrawal of funds. After all, all our actions are reduced to getting income, so you need to put your balance on auto withdrawal at least once every 3 weeks, without chasing super profits and then start all over again.

Play multiple BTC immediately after entering the captcha and receiving the next funds to your balance. I do not know what this is due to, most likely a purely psychological moment, but from experience I will say that playing in 30-50 minutes, I reset my balance several times. This situation is also confirmed by other participants of the system with whom I had the opportunity to communicate. Therefore, everyone should analyze this condition for himself.

Never increase your fixed bid during a block. If you started with 2 Satoshi, then finish playing this block on this bet. While playing, I tried to increase the bet 2 or even 3 times during a short period of time. The results in 99% of cases were disastrous for me and I, in the last such case, reset my balance with 60,000 Satoshi earned within 4 days. After that, I began to follow all the points of the strategy clearly, and such situations were no longer encountered.

And now directly about the strategy itself. It is based on the well-known martingale betting management system. The meaning of it is to constantly increase the rate by 2 times. Mathematically, it looks like this (in the example, I use the minimum recommended bid of 2 Satoshi):

the initial bet is 2 (if you win, 2 is added to the balance, if you lose, 2 is debited);
after a loss the bet is increased by 2 times and equal to 4; in the case of win 8 is added to the balance (4 of them — myself second rate and 4 — win, 2 of which is a compensation for the loss of the first bet and 2 net gain);
in the case of a new loss (the total amount of 2 bets is 6), the last bet is increased 2 times and is equal to 8; if this time the bet wins, then 16 is added to the balance (8 — the third bet itself, 6-the amount of losses of the first two bets and 2-net income).
In the future, the calculations are similar to the original ones. As you can see, if the next bet is constantly increased by 2 times after a loss, the possible income remains the same and is equal to the original bet.

And now, the most important thing about how I play the system in multiple BTC:

the initial bet is 1/2000 from the Bank, used for a balance of 4000-5000 Satoshi (in the future, for a balance of 100000 Satoshi, use the 1/3000 bet for full confidence);
I usually start with the "BetLo" number range selection button (I don't know why, but this is more comfortable for me);
"Youwin 0.00000012 BTC!"(the win) — click again on "BetLo" (following my system, the transition to the second button is after 2 wins at the moment when the expectation and the probability of reverse number increases; from the point of view of probability theory, this is not the right move, as between the ranges still have a gap of 500 units (5250-4750=500), where may be the next generated number, but the system worked great and it was under such circumstances);
"Youlose 0.00000006 BTC" (loss) - increase the bet by 2 times (the "2x" button) and click on the "BetLo" button again»
in case of another loss, repeat the previous paragraph;
if you win on any of the increasing bets, go down to the minimum bet using the "/2 "button (much more convenient than entering from the keyboard), clicking it the required number of times, and then click again on the previously selected "BetLo" button»;
in case of loss, we increase the bet again by 2 times until we win; after that, we start again with the minimum initial bet (the condition for two wins in a row with one button is not met);
for a long series of 6-7 losses, pause for 5-10 seconds before pressing the number range selection button (I don't know how or why, but it works);
if you win (the condition for 2 consecutive wins with one button is met), go to the second button (in this example, this is "BetHi»);
then all the previously described actions are repeated.
As mentioned earlier, the game in each particular block is played from the initial bet and it does not increase. This should be treated strictly and if there is a desire to even slightly increase your bid, you need to find the strength not to do it. I myself fell into a similar trap when the balance is already enough and 1/2000 is the next value than the size of the current minimum bet. After the change, I was in a long losing streak 95% of the time. Therefore, once again I give the characteristic of the " block»:

The minimum length of the game is no more than 1 time per hour with a bet of 1/2000 of the balance with a fixed amount of expected income.

I usually determine the amount of income in a block by multiplying the minimum bid by 30-50. That is, you need to get 30-50 winnings in one block. For a bet of 5 Satoshi, the block is 150-250 Satoshi, for 20 Satoshi-600-1000 Satoshi, for 100 Satoshi-2000-5000 Satoshi, and so on.

In General, the system is easy to understand and use. Thanks to it, at the moment I win 2-4 dollars within 5-7 minutes.

If you don't succeed the first, third, or even fifth time, don't get upset and stop. Just earn a new balance of 4000-5000 Satoshi and start playing strictly according to the strategy. Do not forget - this is a game, and even more so-an online game, so no one can give you any guarantees. Treat it exactly as a game and don't flirt. Because there is no guarantee that a winning number will be generated after 9 losses. Play 1/2000 of the balance and if you lose 10, stop and rest. You will have about half of the balance on your hands, which you will start playing again after an hour. I do this and my result is an indicator of that. In some cases, after a series of 7-8 losses (and this is a loss of 6-12% of the balance at the rate of 1/2000), it will be better for you to stop and start the game again after 1 hour. It is easier to lose 10-15% of the balance, which will be restored within 1-2 blocks, than to half it, and in the worst case — to reset the balance.
