I never understand what a preroll is..
Mind Explaining that to me?
It is indeed a gamblers fallacy.
Imagine you start your bet with 1 satoshi, and you get a 20 losing streak, you bet:
1,2,4,8,16,32,64,128,256,512,1024,2048,4096,8192,16384,32768,65536,131072,262144,524288
Which means you wagered and lost 1048576, now you're busted because you don't have enough money for the next bet, but lets say you preroll 5 rolls, you bet:
1,1,1,1,1,2,4,8,16,32,64,128,256,512,1024,2048,4096,8192,16384,32768
Now you've wagered only 65539 and assuming the same bank, have enough for the next bet. So basically the fallacy is that you wont end up with a 25 losing streak, which is entirely possible of course.
As the guy asking for it intends, alot of people use prerolls with very small bets then hike their bets up to very large amounts. Same kind of fallacy
