Definitely a scam, they're promising instant payouts. They just found a less obvious way to phrase it so that it looks a bit different.
Why would anyone take a loan that they pay back instantly?
I would be extremely cautious about any kind of bitcoin investment that is fresh, we have had many sites (hyip/cloudmining) that were alive for 2 years, and after that period of time it has turned out that they are ponzi or just a regular scams.
The same thing is about xcoins.io, their website is a fairly new one, and not many people have heard about it.
Also, if we consider their features it is starting to be a little suspicious as you say, for me that definetely looks like a scam.
I suggest not touching xCoins.io for some time, it is rather hard to say if they are trust-worthy because no one knows them.
A smarter move would be just to get into it after the time when we can be sure that their services are legit.
