An offer to give away 100,000 sats was posted two weeks ago by Twitter user "hodlonaut" to initiate a game of sorts where the first trusted person to respond with an invoice would receive the payout contingent on the promise that the recipient add 10,000 sats and send the new sum total to another user who promises the same and so on. The experimental game has now accumulated more than 3.5 million sats and users continue to pass the growing pool of funds forward with the #LNTrustChain hashtag.
