With BTC prices decreasing steadily - do you really expect someone to give you a -% rate?
Be realistic .. try +0% to start with - if you're lucky, some weak hands may fold and you can capitalize.

Is your buyer from a mentally disturbed/challenged "institution" ?

At least one reached ATH 3-4 months ago and then declined..the other reaches a new ATL everyday 

Escrow with Paypal means nothing. You will screw yourself over as the buyer has plenty of time (post release by escrow) to lodge a dispute and claim his/her funds back.
Paypal will almost always rule in favor of the buyer as far as crypto-fiat exchange is concerned. Research the facts before losing your coin.

Also, you have another thread with the same content at: https://bitcointalk.org/index.php?topic=3267805.0
You ought to have bumped that thread instead of creating a duplicate.

What does your IQ have to do with BTC exchange ? 

Your final point "Please DO NOT contact for small volumes" IMHO is the nail in the coffin.
If anything - you should start selling small - build reputation and trust here, then people will take you seriously.
Even if you are legit - your T&C's would dissuade any potential client.

Signing a message from the address holding the coin means nothing. It doesn't necessarily mean you own the coin - nor can it be proved.
However if you conduct small deals with members here - we can link their addresses with the outputs from your wallet.

Thanks.

Infact, I am currently working with and trying to implement a Sovrin solution - that's why I think these 3 current solutions are only in it for the $$$$...they lack substance as far as true DID/SSI solutions are concerned.
The people behind these projects are opportunistic alright as they have realized the KYC/AML/ID management to be a major bane...and now capitalized on it 

82 BTC = over 500K USD in instant payment from Nigeria 

HODL till it is listed.
It won't have any value until people start to trade.

Nobody has labelled you explicitly as a scammer. Sure there are similarities in terms of traits though. The biggest problem here, quoting you is "I am not the owner of BTC".
Take a look around - the modus operandii of scammers are: 1) The offer to buy/sell insane volumes; 2) If they sell - they cannot sign a message from the address that hold the BTC, 3) MITM scams - where they "broker" deals but disappear with the coins + money.

Even further you state "95% of our transactions are through escrow" ...what happened to the other 5% If its not 100% - its not good enough.

Do you know anyone (very good and trustworthy friend/relative) that has a business account (if they conduct business globally- that would be perfect) which you can use as an intermediary to send to the exchange?
I'm not sure how strict the financial controls/regulations are in Spain - but I am pretty confident that there will be less scrutiny if a business account is involved.

Anyway- what I can recommend for now is to try with 100K on Localbitcoins...BTC will shortly rise in value again - get as many as you can while the price is low.

I'm selling fMerits if anyone is interested 

Something of concern:

Total CEDEX tokens = 100 million
Total available through presale + ICO = 50 million
Total sold thus far = almost 26,2 million
Total left before ICO ends = about 23,8 million

Your whitepaper states "Any tokens offered for sale to the public and not sold will be destroyed". (**Point to remember !!!**)


Let's be honest - your ICO event isn't doing well : you have only managed to sell just over 1 million tokens in roughly 2 weeks.
I will be generous in assuming maybe another 3 to 4 million in the last 2 weeks will be sold (I'm sure you will have further bonuses during the last few days ) - so let's make it a round 30 million that will be sold.

Now here's the worrisome part: 50million - 30 million = 20 million tokens will be destroyed (more or less) !!!
Then to add to this, there are 50 million still stashed in your reserves which weren't available for purchase - what are your plans for this ?? Then again come to think of it - this is a rhetorical question - you are going to dump them on the exchanges right so you can make a nice profit!!!

This leads us back to the point I made earlier regarding a softcap - and now illustrating the importance of one further. You don't have one purely because you are playing it safe: if you don't reach it - you will have to return the funds collected, and that way you won't be able to "cash out" the 50 million tokens stashed.

Is it my over-creative imagination or someone's bluff being called??

I'm also from South Africa and contrary to what people believe - our exchange controls are far from "archaic" - trust me to know..I live here. Sure there is tight regulation comparatively speaking but there are loopholes that can be exploited. The only truly restrictive condition is that of the taxes paid on incoming and outgoing payments which is slightly more exorbitant than is the norm internationally - that is if using SWIFT. Of course we have our "ways" to get around this  

One the positive side - people are starting to get into crypto and I see trade volumes increasing on ICE3x and Luno (both local exchanges). The biggest potential though exists on LBC - there are people who have thousands of completed trades just by selling BTC in cash at between +10 to +30% !!! That is an insane profit margin !!!

If anyone is interested in bulk arbitrage hit me up - but please be serious and legit, escrow is a must.

One last thing: Brazil, Russia, India, China, South Africa have formed the BRICS agreement/treaty/?. Learn about it - and what it means to do bilateral trade/business under this sphere 

It might be worth signing up to a credible exchange with large BTC volume (Binance and Bittrex are good options).
You will get IBAN/SEPA/whatever details required in your exchange account and you can deposit the fiat to the exchange.
Then you can open a trade for 50 BTC and probably have it filled in a day (a few hours most likely).
Disadvantage: You might have to undergo more intensive KYC processes though as you would be a high volume trader. This could take a few days or weeks (you would be able to deposit and trade, but not withdraw till the KYC is completed).

LBC is convenient, but as you have already experienced - the local sellers would most likely not hold that many coins. You would probably have to make many deposits to different users (they are also restricted by limits) over a few days to get 50 BTC. I have personally also found that LBC can often be expensive.

If I were you, I would try the exchange route - unless large cash deposits attract attention in Spain. You are sure to also save alot as you will get your BTC and pay less than 0.5% trade fee in most cases 

There is an average of about $4 billion worth of BTC traded daily and $100,000 of B2X.
1 BTC = approximately 340x B2X. Your 10x B2X isn't even worth 1 ETH 

Anyway good luck selling your B2X.

If B2X "is the future" - why are you selling them? 

500 BTC for USD in Moscow lmfao 

Yeah rite...and I'm selling 10 kilograms of gold in Nigeria for CNY.

Man these scammers are lame nowadays.

1. Why can't you back test?
2. Who provides the funds for trading? Are you expecting forum members to test your bot at their expense?
3. Has the source code been audited - and if so, where is the report? How can we be sure that the funds aren't "secretly" sent to your Binance wallet - under the excuse of trade loss?
4. What platform is this bot running on? I don't see (either online or on their app) where bots are supported.

Use an escrow- I will give you $10,000
