Just a reminder,
EtherBTC wants to be a better than Etherum and Bitcoin combined cryptocurrency.
They now open their Pre-ICO to registered users with some Bonus.
I already got some free ETHB for having registered and claimed following one of their email.
I still feel critical informations missing on their website (dev's names, whitepaper, etc), but have a look by yourself and do your own due diligence.
Good Luck
