Not gonna watch and waiting for a telegram for waiting for 5$ ~XD It's better to do something else, more prefer share the bonus by email without time duration so everyone got the chance to claim. Win and win solution, the most important things everyone is happy because can claim the code ~XD.
But, when they gamble 100k times and fail to get 1k once? They suddenly start to act like there is some shady stuff going on . Dude, it is gambling and you have one in 1000 chance to get it, obviously it is not going to happen very frequently anyway, and sometimes it is going to be even more unique. Just get over it and realize that each bet is different from the previous bet. These people will never learn the true value of gambling and will only play with their own perspective in mind.
