Are autoexchangers usually a scam?

[SatHunter]

I saw something recently about auto exchangers, and I was wondering how legit they are? The one I looked at is ChangeBTC.bit, they say they automatically exchange btx to eth.

It sounds so easy to use them, but ...

I have never heard of that one, but just because it has somewhat of an odd domain name I would avoid it just in case.

Shapeshift so far has been the most trustworthy on that front, but they unfortunately will force everyone to create an account and verify themselves very soon. The danger of this is that people will suddenly try out unkown services pretending to do the same, but without the verification nonsense. We'll get a situation similar to complying exchanges versus non complying exchanges, and that's not really something to look forward to.

Another negative aspect of these newer services is that even if they aren't a blatant scam, they will only complete the trade if they have the better end of the deal. It means that if the price suddenly drops, they won't let the conversion happen till the price recovered. Changelly does that as well.

Also from that I know autoexchangers are usually more expensive than the well known exchanges, although it depends on the amounts too (because the exchanges also have the withdrawal fee)...

About being a scam or not, try to use services for which you can find feedback from users, the more the merrier...
