....
Its like stage 2 people are reserving coins (with 0 cost and risk) that would have been split among stage 1 people. If the coins profit, they take them. If the coins lose money they can decide, after the fact, to dump those coins on stage 1 people.
.....
But 1st stage people can DUMP before 2nd stage guys will come to party, they can dump so hard that they will have less than ICO price(seeing realty shitty wallet).
1st stage people have 1st opportunity to get out before 2nd stage people will have chance to dump.
If DEVs deliver poor beta wallet 2nd stage people are in ass, escrow have to release founds while 1st stage people are dumping hard to 0000 sat.
Whole point of escrow was to protect people from scamming devs that mean taking money away releasing 0.1BTC wallet to dump and vanishing...
