Well, lets just say that people actually react to problems or situations in different ways, both in words, actions and dids, this is what makes up different and unique as humans, personally I would blame the user for the outburst, that's probably the best way he thought to react to his missed opportunity, even though he either knew or didn't know that his outburst won't change anything.

The world of cryto currency, which also now cuts around the gambling industry is a very fast moving world, and lots of people miss a lot of opportunities everyday, most especially the active ones, this is why I always tell my friends who are interested in crypto, as well as crypto gambling casino, airdrops, giveaways and so on, that it is mandatory to always be active, because a little sleep or slumber, you just might wake up to discover that you've missed out on a very good opportunity, one that sometimes could be life changing.

So, the user should blame no one but himself for no being online and active to claim his bonus when other were claiming theirs, all he should do is just learn from this experience that both time, opportunities and rewards waits for no man.
