Stellar Lumen Distribution
On March 28, 2017, The Stellar Development Foundation announced
that they will be distributing up to 16 billion lumens (the token for the Stellar network) to holders of bitcoin.
The foundation will take a snapshot of the Bitcoin network on the first block mined on June 26, and will subsequently publish a claims page to allow bitcoin holders to verify their control of their bitcoin and claim their lumens.
Since Coinbase stores most customers' bitcoin in offline addresses, it will not be possible to prove ownership of any Bitcoin stored on Coinbase to take advantage of this distribution.
If you would like to participate in this distribution period you will first need to withdraw any bitcoin you wish to an external address you control before
