I'd be suspicious of them, at best. I've asked them a set of questions twice. They haven't responded.

You have no idea how many red flags this is sending up.

1. You fail to provide a suite number for your address, since 444 Brickell is a large office building from what I can tell. This doesn't prove that Bitcoinera has a physical address.

2. From research on Christoph Zeras, the contact person, both places of residence listed are over three and a half hours away from Miami, where 444 Brickell is located.

3. Your website states that you have a team consisting of "major players in the bitcoin economy, some of the biggest localbitcoins.com traders, investors, gambling site operators and more", which gives me no security that anybody like that is involved. I don't know any names from this. Also:

4. The only Christoph Zeras I could find works for RingPower, a subsidiary of Caterpillar. It's possible that Christoph Zeras is unlisted, but that just makes this even more sketchy.

5. Calling the phone number provided says something about a "Bank Contingency Mailbox", and that any messages will not be retrieved.

This begs the questions. Who the hell are you guys!?

It's suspicious as hell. Also, they decided to instead respond about how bad Inputs.io was. Now don't get me wrong, I'm not defending Inputs.io, but they decided to use Ad Hominem to try and refocus the conversation.

Also, a quick search for "Christoph Zeras Bitcoin" returns only press releases about CoinEra.

Also, the reviews on CoinJabber are 100% negative.

Be careful, and use common sense.
