Ah yes the no technical person wanting explanations for benefits and reasons why not gone for the very technical new development that everyone is excited and talking about.
I would almost approach this from the other end where the limits of a decentralised exchange.
In this case your decentralised exchange has no sole person responsible and thus accountable for the software tat is running their business. When something goes wrong and people want to speak to a manger / person in charge etc. Now by running a centralised exchange you get to promote YOUR exchange and your face name business profile etc and can have full transparancy and not be accused of hiding behind decentralised code or anonymous users / investors / developers etc
Secondly you in a centralised exchange have put your company name on the line and this can be very powerful in itself. Remember the Winklevoss twins and how they bought a load of BTC well any time btc was on a rally or price goinjg up in the early days these 'big' names become important to offer credibility and a familiar name for people to read further into and investigate. Your centralised exchange can offer to do this with your name again. Base example but I would be interested in seeing what else say Bill Gates has produced if I am going to use this Windows Microsoft computer... and I am not sure who has developed my decentralised computer or the code behind it thus I would be putting trust in someone else research or trust...
I'm sure there are some other legal advantages also... ie tax writeoffs, claiming tax back and limited company insurance that you would be eligible for if you ran your exchange as a standard business model etc but I bet the tax man or other legal bodies will be looking closer into your decentralised exchange when you start turning a tidy profit etc. and this more than likely a bit of a grey area for legal standings etc till time passes.

Thank you. It is nice explanation and agree that, from technical point of view, it is much more difficult to create a 'close to perfect' Decentralised exchange..
In my case, here problem is, investor being a not-very-technical-person, is looking at de-facto "Dex is better than Centralized". Definitely I can explain, how difficult it is to implement codes in better way. But every week or so, there has been new ICO announcing that they are coming with DEX. Many of them are not capable and just for the sake of attracting investors and create hype for their ICO sale, they anyway announce their idea. But investors are listening DEX more frequently.
Now, apart from explaining that we are not coming up DEX due to technical reasons, are there other benefits of Centralized, which can be explained ? Like, in centralized, trading fees would benefit him, as investor ? Or any more reasons to say, "We want to come with Centralized now, and DEX later" ?
