There are people who never buy into icos like myself.
If i want to buy a position in such a project i go over to bitmex and buy a future contract so i don't have to put my money into a black hole, download wallets, trust devs, be locked in my position and whatnot.

The future contract i can sell at any time, am not locked into the position and only need to trust the established exchange, not some random devs.
I'd recommend people buy more futures than they actually buy the icos.

You'll get a discount on fees if you sign up via my referal link:
