You got it, not that it'll do you much good.

I think they're gone for good. 


No, if you see on the left where it says "Make sure BTH is ...", the BTH is clickable and gives you information about the token.    This is Bytether: https://etherdelta.com/#BTHE-ETH

That was Bytether paying Oracalize for the lookup to their website.  However, it was Bythether's ether, not yours. 

I wanted to learn a little about Solidity and Ethereum so I had a look at the Bytether contract to see what it was up to.

First thing is that virtually all of the technical differences on the comparison chart in the OP are due to Ethereums's features.  BTH is just specifying the total circulating supply and launch date.  They haven't developed anything technically significant.

They briefly mention a "user growth pool" of 3m BTH.  I don't see them mentioning that there is also a "developer fund" of 1m BTH.    Both of these are created on top of the 17m bitcoin they're intending to crossfork.  There is no attempt to hide any of this in the code, it even has relevant comments.

The contract uses the bytether.com site to get the amount of BTH to be given.  The contract itself makes no attempt to verify this information, it simply trusts the website and also trusts oracalize.it to relay the information.  They claim that they "cannot" assign BTH from the crossfork pool to any accounts, but that is technically incorrect.  As they control the website they can have it reply with any results that they wish.  As I don't see where they list the signatures they have received there would be no way to know if they were assigning themselves BTH for bitcoin addresses that they do not own unless they happened to be caught using an address they couldn't possibly own (note I haven't seen any evidence that they're actually doing this, nor have any reason to believe thay might be).

The fact that the crossfork process relies on the website means that any attempt to crossfork will fail while the website is down (as it currently is).  There are quite a few pending transactions and they will all fail if they get mined while the website is down.

I don't see them mentioning whether they evaluated using a merkle tree of the UTXOs at the time of the crossfork instead of relying on the website.  

The contract contains the ability to freeze accounts.  It also contains the ability to automatically buy/sell BTH, although its BTH balance is 0 and this feature is currently turned off.  Their revertCrossFork function can be used by moderators at any time to remove a crossforked balance from its initial address.  

The ability to crossfork can be turned off in the contract.  They haven't mentioned when of if this will ever be used.
