They have to actually pull it off. If they can deliver what they promise, this will be a very interesting exchange. If not well....nothing lost

Always an excellent question to ask!!

Do they get your email that they will then spam?
Do they use this opportunity to sell you more of their currently worthless coins(tokens)?

Never had a problem with spam, I have a special email account for these kinds of thing and gmail handles spam quite well. So I am not worried about the spam. And I ain't buying until I see some proof that this baby is taking off. But for now I am holding some free coins and gonna wait to see what happens.
