I just have incidentally read about this stellar giveaway, based on the blockchain snapshot taken some hours ago,: I have a wallet with a bit of BTC in it, may someone please explain/address me to steps I have to take to claim this stellar/lumens based on the BTC owned?
Thanks in advance
I am using Electrum two factor Authentictation wallet which is P2SH start with 3.
Any one can support how to claim the Stellar, is said 'For P2SH (multisig) addresses, you will be asked for a redeem script'
How can I get the redeem script?

Thanks.
I have used Mycelium wallet to outline the steps, but it should be pretty similar for the bitcoin wallets.
I have written a simple step by step tutorial with images on "how to claim free stellar" for those who are not familiar with Bitcoin wallets sign message functionality.

https://steemit.com/cryptocurrency/@sniperz/tutorial-how-to-claim-free-stellar-using-mycelium-or-any-other-bitcoin-wallet-with-imagesI have similar situation like you ^^^. I just missed the giveaway although I was having good number of Bitcoins in my possession. I just came across for updates and saw someone asking about snapshot which was taken yesterday. Anyways I made good profit from last day's crash by buying at lower and selling at high. Next month I will be linking my bitcoins to get from free distribution. Hope it didn't reach to its limit yet.
I don't think there is another snapshot for the next month.
If you had BTC in your wallet before 26th June then you are qualified to claim .
Claim ends on 27th August 2017.
