It's just one promotion though there's still a lot of promotions left to join and some of them are risk free.
Let's say a store in your area runs a bunch of ads saying they are giving away big screen TVs, and then when you get there they say "nah we cancelled that, but you can still get $5 off of a fridge". You'd be a little irritated.
LMAO.
You have no right to be irrated at nitro. Be thankful that they paid out the first two promos.
That's a bad mindset you have, and bringing it into the world of cryptos and/or the world of gambling is going to leave you taken advantage of.
Don't be a sucker.
If someone promises something, they should stick by it. Yes, it's understandable that they would cancel a promo that would lose them millions...but it's still irritating.
