I am brand new here, but I've been lurking for about a month now since I got into crypt. I honestly think that the speculation should stop. It's just paragraphs of useless data that I'm trying to sift through to get an answer about the status of CoinsMarkets.com.

If you have NEW information or a joke, I think those are welcome. Otherwise, you're just beating a dead horse and saying something that was probably said hundreds of times before you in the past 60+ pages of this forum.

If you don't like my suggestion, then by all means continue. I'm just suggesting something that is mentally healthy for you. I want to make people happy. That's my life mission. Crypto is just another way of doing that.

Stay positive guys.

Every time a block is mined, a certain amount of BTC (called the subsidy) is created out of thin air and given to the miner. The subsidy halves every four years and will reach 0 in about 130 years.

Looking in the Chrome console, I found what's is DDOSing their site: is the ajax request that don't have a timeout control when a request return a error, after a erro the site make immediately another request without timeout control.

So for any server they try to setup the site will overload and consume all resources in minutes.

They need to change the ajax request and make an error control, when returning a code other than 200, impose a timeout on the next ajax request.

For example, hundred of this requests are mede per second when a RESOURCE ERROR are returned:

 GET https://coinsmarkets.com/getbalancebuy.php?coinid=5&name=Bitcoin&pairid=1 net :: ERR_INSUFFICIENT_RESOURCES

If possible, send this information to them: add error control and timeout on ajax function, to delay request on error.

And to get thinks worse, because the amount of request made in the loop, cloudflare immediately block the user, that explain why we get a cloudflare error page after few seconds, if they add a timeout on a error returned on ajax, they can stabilize the site.

Yes, that makes sense, if they are using InnoDB or MyISAM and the database are corrupted, take hours or days to rebuild the database. Every time the process are interrupted on server crash, the db must rebuild again.

But, they must immediately add a timeout to control ajax requests, this loop are killing them.

A pro-tip to recover a InnoDB database: start the mysql in read-only and use innodb_force_recovery>=1.

Dump de database using xtrabackup and then use xtrabackup --prepare to make a new database.

I prefer this approach for very large databases, because is impossible to rebuild indexes or to dump large database to sql file.

It is really taking them longer to come back into the business, but I still have firm belief that those people aren't scammers. I have had some amazing trades at their site, and everything was working fine then, but suddenly that "ECA" came into action, which almost made the investors greedy.

Because of huge demand of "ECA" the site became overloaded and slowly started giving errors. But, it was working even after those errors for 1-2 days. After, that the site went down with some messages like "Due to server overload, we are migrating to new servers, please bear with us". Those messages were really annoying at the beginning but gradually investors started believing that those messages are just fake hopes.

WOW... I can't believe there's yet another "excuse".

I think these guys are actually TOO STUPID to be deliberate scammers..

Someone needs to inform them though... that its ok to accept some assistance.

If coinsmarkets was a scam, wouldn't we start seeing a massive dump of these coins they stole onto the other exchanges as they liquidate their holdings???

We would've seen a dump yes. But, now we have to wait longer for them to change service providers due to to unnecessary calling of their provider by frustrated users.

Unnecessary ? ? ? ?

There's quite a lot of people ready to disagree with you here.

you can't expect to withdraw a service & then hold peoples money without any sort of communication or explanation !!

At least One lesson to come out of this farce is that Dev's, Provider's, hosts etc should now realise that silence is no longer an option...........

i hope they would be back online asap.

i think if they're out of cash. the website could offer monthly subscription to its users. just a small penny. for example 10usd per registration.

also they would implement coin listing for a fee of 1btc so that they could maintain the site and be it forever a cash cow for them. also so that they will never stole funds

from their users. take a look at cryptopia right now. they were like coinsmarkets several years ago. they survived because of the fees they collect from coin listing.

If he enable withdrawal, he can earn massive amount from fees. Then, after site fixed a lot of people jump back and he can get another fees regularly. It will be more suitable for customers and admin.
