Q."Can I keep coins on bittrex for snap shot day!" No. We don't advise it.

* Send coins to Cryptopia if you want an exchange to handle the airdrop for you.
* Send coins to your Spreadcoin wallet
* Send coins to a Spreadcoin address where you have access to the private keys, in the event that you have not downloaded the wallet in sufficient time to fully sync the Spreadcoin blockchain.

However, we have made Bittrex aware of the snapshot block height. We have also offered to provide them with support for any coins left on the exchange at the cut off block height because people were away, sick, etc. You will need to open a support request directly with Bittrex and ask them to send us an email, detailing the number of coins they want and your exchange address.

This does not mean you can leave your coins on Bittrex if you want to claim your Helium coins. The only officially supported exchange for the snapshot is Cryptopia. Bittrex involvement at this time is down to their goodwill if you have a problem. We cannot get involved with the process, other than to accept a request directly from Bittrex. You may have to wait a while for your coins to be processed by them and then us.

see #snapshot thread for other questions asked about the snapshot. Please do not post in that channel so people can find answers quickly.
