Lol stop showing your teeth there is actually no such a thing as rapidly increasing , 99% of them are just wolves in blockchain dev skins, pre-mine or throw you an ICO and that easy they get their millions of dollars, maybe you are also interested in doing that?
First BTC then ETH and then you could literally launch any token on ETH thanks to Vitalik the butcher .
To answer your question they are making millions dude, haste towards the fortune before it's too late.
