ovextrade.com appears to be a scam.  

Their "about" page claims they've been around since 2014, but then contradicts it's self further down the page stating they were founded in 2016.  According the the WHOIS data the domain was created on 10 OCT 2019.

The Terms of Service page is plagiarized from this site: https://exmo.com/en/docs/agreement

According to user Mosperian ovextrade.com requires a deposit of 0.015 BTC to make a withdrawal of funds that are already in your account.  He was directed there by loan scammer.

They are probably using this fake exchange in combination with telegram and discord, where they send PM
and they tell people how they won XX btc, so they need to register and find out that first they need to deposit bitcoin, if they want to withdraw.
Everything is fake.

Recently I reported similar thing with this:
Coinxkeep
https://bitcointalk.org/index.php?topic=5193065

They are for sure inspired with them, but I can't be sure if they are the same behind this scam.
They mostly use Discord to 'promote' this

Interesting, looks like they are massively cloning those sites using the same script, my question is if there are reports of scams already.
I also found this one using the same script https://www.coinbeaxy.com/  --  Warning, dont visit the site, is probably a scam

Watch for this site https://cryptotradego.com/

Its a SCAM and i got burned very bad.I found a username and password in pastebin.com and entered them and i saw there over 5 BTC.And then i started chating with the support thinking it was a real support.I paid 0.02 BTC to start withdrawing,then 0.035 some insurance and at the end he/they wanted me to deposit 0.05 for Premium account.And i got confused but it was ro late.This is why you must double check sites where there is no security(just the telegram security code).Anyway i searched and found the number of the company,but it is one with expired day.Company Number was OC393265 which is for LA CLOTHING SOLUTIONS (MIDLANDS) LLP.

I have same cases,someone says he from china (use telegram chat) he need to withdrawl and will be give me fees.  He sent 0.8btc and he says to me  to be make account in this sites.. please check.. Hurtrade.com.
The sites display s same as the other..SCAM...

Hello guys, I was probably just made up by the same guys... same Company.

www.indexi.net

I will be checking it out. I have got some aces on it... And would like to ask you for suggestions.
 What I mean is just ... If you would have this possibility, how would you proceed to be able to oppress them and then put them down?
  If somebody is here around, eaze the mind, and tell few ways, how would it be possible, I will try to put the people together, based on these proposals, and make something real from this. Just for slight revenge.

I wanna know who they are, where they are, how they communicate, what can be their weakness from what you think you know.
 Will keep you informed ... Supposing you will gimme some ideas. And no stress, I have got great overview, so do not be affraid to be silly a bit.
 Just tell me the border lines.. I should be able to overtake it based on this.
 (personally have some idea, but wanna hear more... ) 

I don't think you will be able to track them down minus spending lots of money. Best thing to do right now is to just create scam accusations as their domains don't stay online for so long

They usually create hundreds of more similar domains like the one @CharlesWard  just reported here. So the scamming doesn't end at overtrade.com going offline.
