The semux airdrop is a giveaway to bitcoin holders. If you held any balance @ block height 480,000 you can claim free semux.
Unfortunately, in order to claim you do need to download a number of files as well as the semux wallet (which could be unsafe) and it's a bit of a pain. I have the semux client running on a PC by itself and it's worked well so far in claiming and sumping SEM coins.
I'll admit that the title is a little clickbaity (and simplified),
The exact rules are that if you had 0.05 to 1 BTC you get 20 semux
If you had anything less than 0.05 you get 0, 0.05 to 1 and you get 20, and if you had > 1 BTC you get 20*(whatever your balance was)
The message you need to sign (for me) is: 0xcb63a0fcd1550d80d7ce0fa511abe1c81bea7622
After you sign that, you can either pm me or reply to this post with the signature. I do not need to know your public key in order to claim.
Notes:
I will keep a public (and private if requested) ledger of everyone who claimed semux and I will send Bitcoin to whatever address you request.
Semux are worth about 0.0001-0.00015 each and so I'm willing to sell them for the best price I can and then take a 20% commision, this will return you about 0.2% on all your BTC.
Giveaways are on Sunday, they will be sold the same day, which means I'll also send out BTC to those of you who sent me a Bitcoin (withdrawal) address and your signature.
*Why should you trust me?* I am not a longstanding bitcointalk member, but I have been involved in a number of other commmunities for a long time, if you would like references to people who would reccomend/vouch for me send me a pm. I suspect you'll be satistifed, but I can also prove trustworthyness in other ways.
Also, there will be a .0001 BTC fee subtracted from your amount for the tx fee, so please don't try to claim dust.
