I didn't like that official e-mail where the team said the token sale was expected to be fully sold withing 24h given the huge demand, so we needed to hurry. Very unprofessional, in the boundaries of some scam messages we see in slack. The team must take care with their language if they want to be considered professionals. Reputation is everything!
You see word "expected"? That's not unprofessional at all.
It's like BTC was expected to reach $5k last but sadly it didn't. Whose fault is this?
it's called building expectation and the scarcity principle. if people perceive that something is rare they will pay more for it and buy it asap.
