I've been a seller on xCoins.io since Sept 2016 and I have loads of experience with the platform, so I'm happy to provide feedback on that experience.
It's a great and unique platform with several flaws that you absolutely MUST understand if you intend to use it (otherwise you will have a lot of difficulties).
I'll list the pros and cons below, but overall, I recommend that people try out the site
only after they have educated themselves on how it works.
Ignore the 'Loan Bitcoin' thingThis platform is for buying and selling Bitcoin. Buyers pay by credit card and sellers collect their funds via PayPal (other processors will be implemented in future). The business model used is actually quite similar to LocalBitcoins (but xCoins handles the BTC transfer and buyer verification). Sellers charge a premium of not less than 15% (not including other fees). This may seem high to some people, but there are not many other places that you can buy Bitcoin with credit card quickly. AFAIK the 'loaning' thing is just semantics, so they can call the profits 'interest' to avoid regulatory issues.
Automated tradingSellers set up their account and trade preferences, and set their account to active. xCoins automatically matches buyers and sellers and will keep doing so until you hit your preferred limit or run out of BTC (at which stage you need to top up your wallet again). It's a nice system and pretty clever.
ChargebacksBuyers will occasionally try to defraud you by initiating PayPal disputes to try steal back the funds they paid. This happens regardless of whether you are selling BTC or shoes on Ebay and if you use xCoins, you WILL encounter this issue. However, there are ways to mitigate this issue (which, for the sake of brevity, I will not detail here), but you really need to understand this before you start. Scammers are automatically banned from xCoins, so fortunately this isn't as big an issue as it could be, but some people still try it.
PayPal account limitation
If PayPal consider you to be 'high risk', they may limit your account (i.e. freeze your account for 180 days). Sellers need to be proactive to try to avoid this. Things like having a high chargeback ratio or having a huge spike in volume on a new PayPal account will raise red flags, so this needs to be considered (again there are ways to mitigate this).
ProfitProfits can be high for sellers as the amount earned is based on how much volume you can recycle through your accounts. If you have 1 BTC, you may be able to sell this once each week on xCoins while rebuying on another exchange (the time it takes to recycle your BTC really depends on how long it takes to withdraw from PayPal to your bank account and then get you funds back to a BTC exchange). So the 15% profit is not 'interest', it is profit on sales each time you cycle your BTC.
Counter-party riskThere is always a risk of any online company doing an 'exit scam' and running away with your money. To minimize this risk, only put small amount of BTC into your xCoins wallet each time. I tend to transfer 0.5 BTC to xCoins, sell it, then repeat. I personally believe xCoins are trustworthy, but it is still a good idea to never trust any company in crypto with funds that you cannot afford to lose.
Customer supportIn the past, xCoins customer support has been understaffed and completely inadequate for the volume of users. The forums have been filled with people screaming about the issues they were having and you will find many negative reviews by disgruntled ex-users. However, after around 6 months, there are no credible stories that I am aware of where xCoins behaved dishonestly and in the last month extra staff have been hired and all customer support tickets seem to be addressed very quickly, so things seem to be improving a lot.
CommunityThere is great community of helpful users that are happy to help new users. Most posts on the xCoins forum get answered quickly by more experienced and helpful users.
So that's my overall review. I highly recommend trying it out (with a small sum of BTC at first), but I can't stress this enough...
do your research first!!. All the info you need to successfully use this platform is available on the forums.
Also, although I am recommending xCoins, I've tried to present the facts in fair and balanced manner, so unless you disagree with any specific claims that I have made, please to not respond with unhelpful comments of 'shill' etc. I will respond to genuine questions though....
