this is a little fishy...
how much spark will i get for x amount of btc? will it be based on percent of btc sent to that address? say i end up sending 1% of all the btc invested... i'll get 1% of spark? you should be clarifying how you are dividing this all up. or maybe i'm just an idiot.
how do we know all 1 bill will be released? how will you prove it?
