Purchase SPR on Bittrex or Cryptopia and then move your coins to your local Spreadcoin wallet or to Cryptopia's SPR wallet. If your coins are in your Spreadcoin wallet you will need to manually sign a message from your wallet with your HLM address to the team to receive your coins (will be longer to get HLM doing this than using Cryptopia).

If you put your SPR on Cryptopia (BEFORE OCT 10 @ 10AM NZ Time (GMT+13)) you will receive your HLM on the exchange there. Ratio is 1:1.
