usually they just want to get a big profit by buying tokens with 1: 1, the community and I would want to buy the token, with the price in the market already exists (although the desired token has not appeared)
People want to get free forked coin by buying the original coin, why anyone want to take such a risk ? What if something like NXT happend in every fork coin ? you know right the price droping 60% a minute before fork happend and everybody end up losing money cause chasing the non real unrelease coin, except the whale whu dump right before it.
