How can you use 2 of them, who is actually holding the money and who is responsible for making sure the btc are safe?
This is my thoughts exactly. With the right motivation the site will perform very well and I'm looking into the potential numbers now actually, the massive plus is they need to have a great work ethic and motivation to release the funds raised from the ICO so there is no worries for me. From my little knowledge having a 2 of 3 escrow is very very safe.
The devs hold a key, each escrow holds a key making 3 total, there needs to be two of them keys to release the funds making it much more safer than just one escrow holding the funds. If one escrow was used and he ran or got 'hacked' then the money is gone Using 2 of 3 if something happens to one of the escrows, the other with the dev can release the funds upon completing the milestones they have set.
You mean I can have a wallet, with bitcoin in it and have 3 different people who can use the wallet but two of them need to be there at the same time. Where can I read more about this.
You need to spend more time in the beginners section and not in the altcoin section dude. Its called multisignautre wallets.
