IMO, you should stop gambling on dice sites because I think that almost all dice sites are rigged and are there just to rip off your coins from your account. Whether you gamble at 50% or 1% or 99%, luck will never favor you and house will eventually take everything.
Yes, many dice sites use fake seed and have full control provably fair system, they can make to lose easy.. and players lost all money.
playing on dice - result is one - lost all money
In fact, this effect is achieved through quick search methods for collision hash functions developed in 2004-2006. If one does not know the collision are two different sets of data having the same hash value. So, in 2004, a group of Chinese researchers developed an algorithm based on differential cryptanalysis, which allows for a relatively short time to find two different random data block size of 128 bytes each, having the same md5 sum. Although this algorithm at one time produced the effect of a bomb of his performance left much to be desired. But already in 2006 Czech cryptographer Vlastimil Klima offered to search for a new collision method to find a couple of different random 128 byte blocks one md5 sum of a personal computer less than a minute.
it's possible for md5, sha256, sha512
I do not blame any dice sites.
