Why would someone ever want to donate so much amount as to make it up to 10 BTC
If you really think you can reach this goal , choose a proper Escrow and talk to him and always send small amounts you have to him and when you think you have collected enough , ask him to give you
the only problem i have with this is that escrows are humans too, they die and if they die, my btc dies with them, i've always had this fear when dealing with people over the internet, if the forum takes the money and keep a record of how much i have donated, I'd be happy with this, i think that even if theymos dies, this forum will go on
Hahahah that is such an absurd fear but it can't be denied .
I think you can discuss about a multi-sig Wallet with a Escrow .
There will be 3 keys , one with you , one with Escrow and one in a bank maybe ?
Then if even one of you loose it or dies , there still be two keys and two keys are required to enter the wallet .
