I'm down for 4 as well if I may join.
so we need know 9.5btc more
According to Jani, only one person must contact him for the whole group of 20 btc.
You guys don't know each other, how and who will manage that?
Probably, you should find an escrow for that purpose.
i dont see any problem. one person can contact him via email and put our all emails into cc.
escrow dont needed because everyone of us can send the btc directly to jani.
Where you see Problem?
I thought that Jani want a single payment for the whole group. If he accepts different transactions for a 20 btc group, there is no problem.
You could probably confirm this thing from him only.
Second thing, I was considering is that, some of guys have agreed to bay some btc. What of they later don't contribute the btc.
Make the group fastly before the launch. You can also contact some people who use telegram.
Best of luck! Grab your ICNs !
Edit: Oh! I didn't read that you have already managed to gathered 20 btc and there are no more ICNs for sale now.
You missed the golden opportunity.
i sell you 30k for 3$ each
