Nowoczesne, kapitalistyczne techniki generowania bogactwa, takie jak Bitcoin czy NFT, jeszcze bardziej pogłębiają problem globalnego ocieplenia, wzrostu temperatur, wymierania gatunków itp.

It means some of those people have violated your secrecy.

But I am surprised that the wallet has not been cracked yet given that it is between 4-8 chars with only numbers and letters. That would be easy fodder for Hashcat and a lone (high-end) GPU. Are you sure these are the exact constraints of the password? Maybe there could be some non-latin characters that you have forgotten about?

each range contains 115 numbers cos you can only win higher amounts with the 115 numbers 9886 to 10000, so you can directely compare this results.
The probability to roll 9886 to 10000 is 1.15 % if each number would be equivalent --> 426 * 1.15 % = 4.9 so by chance I should have rolled ca. 5 times 9886 to 10000.

I think the results seem to be reasonable.

But I also did some statistics with my free btc rolls data:

I did 426 rolls within 1 month.
rolls from
886 to 1000 occured 4 times
1886 to 2000 occured 4 times
2886 to 3000 occured 3 times
3886 to 4000 occured 4 times
4886 to 5000 occured 4 times
5886 to 6000 occured 5 times
6886 to 7000 occured 3 times
7886 to 8000 occured 6 times
8886 to 9000 occured 4 times
9886 to 10000 occured 0 times

I have to say there is a good case to be made about getting players back, because new players are unknown, and old players who are still playing are here, but getting the players who quit to comeback would mean that they were here once a while and it wouldn't take too much to convince them to get back and that should be a good amount of money to cover as well.

I cannot say that it will work or it will not work but it is a good idea. Rewarding them for not playing is not the case here, convincing them to come back for whatever reason they quit and just gamble a bit more to light that fire again and earn some more money from those people would be the key here.

i have to experiment that. It's interesting

Yes it is my first Cuda project and i think that an optimisation is possible with the use of the different type of memory of the GPU (Global and shared memory) beacuse the time access are different.

To copy my tables in the GPU mem  i use the standard function :

cudaMemcpy(b, a, ..., cudaMemcpyHostToDevice);
so i'm not quite sure in which type of GPU mem the tables are loaded.

The further greater thing is that, by logic, if they keep doing this, they have to give all 21 million to their users eventually. That is exactly what this means, obviously, the users withdraw, but if nobody ever withdrew, then the amount they have ot pay keeps growing more and more and more eventually reaching 21 million, obviously, this is the technical approach. We all know that between all the people who are gambling, and the withdrawing, we are not going to have anything remotely close to that, this is just the math behind it to make sure that people realize how amazing what they are doing is.

You sure mate, you wanna have million worth of tokens to be locked up? That's just huge amount. I am not sure but while I was thinking about the same, you could just buy multipl FUN token slots and lock them all until its a million. The only question that is needed to be answered by freebitco staff is whether this will increase the current premium features by that much pack size? Like if I keep buying 500K + 500K then does it mean I will also receive 10+10 free spins everyday?

That will be too big for the investors and I think they will invest FUN tokens in other places such as exchanges because they can get another benefit as the investor in the exchanges.

Besides that, I can not imagine how big their chances of winning from the free spins are if they invest 1 million FUN. Maybe that person will get many good rewards from Freebitco.in.

It is one of the highest interest out there and surely is better than probably most bank offer,imagine if you put 3 Bitcoins there and you get for a year much more than you would get in most banks by this period if you put the same amount of money in banks.In the country where I live they are making ads on TV and radios like how huge their interest is when you deposit USD or EUR they give you 1% of that amount yearly.

In this challenge, we all know that the brainwallet is on bc1qt2mdkehmphggajer3ur3g8l754scj4fdrmw3rn. I guess your software should also have an option to set destination address directly, without checking all funded wallets.

It is a lot of better than on a bank account for sure; the 4.08% (or up to 5.1%) is sustainable but it is also not the highest in the market. I have put around 0.1 BTC in freebitco.in a couple of years ago to profit from the interest and I will keep it in there until I really need it.

As @vjudeu said, you used un-optimized tool. You should use optimized tool such as hashcat. Even on single core VPS, i managed to get ~5000 kH/s.
