Had to youtube a video just to learn how to deposit my ETH on IDEX. The user experience is really bad.

Once you connect your metamask wallet it nowhere states that you have to deposit your ETH into their wallet. There is no part of their guide as well that tells you that you have to click on "QUICK BALANCES" just to deposit ETH because when you go to the The "BALANCES" page ETHEREUM IS NOT LISTED. Wasted so much time going to youtube and searching for guides god damn the token i was going to buy already pumped.

IDEX IS A BAD EXCHANGE NO BETTER THAN ETHERDELTA. I hope some IDEX people read this your exchange SUCKS.

Not to mention trading and withdrawal FEES are a RIP OFF.

Yesterday had crossed my mind to sell my tokens at IDEX but luckily I have not sold it, because my friend forbids me to use the exchange on IDEX and this I read the article about IDEX that IDEX is so messed up so I just believe that IDEX is not worth to use as a token exchange.

been using IDEX for a long time and didnt experience any bad incidents probably IDEX is not for people who dont know how to use the internet properly..

They make users face difficulties to transfer. No clear direction like we see in so many exchanges. They have to do more work on the site to assist users navigate easily.

In my opinion, I have been using idex for quick a while. The issue is that, they need some upgrade in their system and they need it to be stable as idex lags a lot. They have a lot of technical issues and this isn't so good for user experience

Idex is not for everyone, really. If you dont know how to be resourceful and learn to navigate the site to find what you're looking for then idex is not for you. In order to know the ins and outs of idex you have to be keen. It doesn't need a genious to learn depositing or withdrawing, it just needs your time and patience.

I agree with you that IDEX is uncomfortable. Also, from time to time I experience difficulties with it. And it irritates me very much. I think they need a lot and a lot to refine it.

First, the IDEX exchange has a good user experience.
However, due to the large number of users, there are more and more problems in using IDEX exchanges at present. However, it is also a common problem for decentralized exchanges.

You made the mistake of giving your opinion of Idex. Idex is a decentralized trading platform, and it is straightforward to execute the load deposit and withdrawal. I find that this is a swap platform for many projects and people opt to list tokens after the end of ICOs.

I think only me and my friends who complain about Idex performance, the most annoying thing is the transaction process that always fails and must repeatedly, it is very mambuat uncomfortable and makes me very annoyed, I think Idex should clean up and improve their system , I hope idex quality as it used to be.

This is a common problem in most of the decentralized exchanges and that's keeping people away from them. It's true that income of these exchanges will be much lower than the traditional exchange but again that would rise with rise in the use and making a good GUI and friendly introduction is just one time work.

I think idex is better and safer than etherdelta and forkdelta. It is unfortunate that the minimum withdrawal limit at idex should be $ 100 and this often traps new users. Its trade costs are also quite high and in one trade we can pay 3 times the transaction fee.

Op, thank you for this information and I think this is an eye opener for some of us that has not open account with idex.  From the beginning my fear has been be able to fund my account through my myetherwallet private keys.  I read a story here how someone account was wipe out by hackers on etherdelta through this method and since then I only used a centralized exchange for trading.

And I am sure IDEX must not be for me since it is not good for newbies who do not have the technical experience as well as the patience looking for the right buttons to click. There are actually many decentralized exchanges like this and though I love the concept of it am always afraid to explore them because I am 99% sure I can only be lost along the way and end up giving up. This is actually the first time I read a detailed complaint on IDEX. well, there are other exchanges in the market so we better not wade into IDEX if we are not that prepared for technical roller-coaster experience. But then again we are all hoping that a good guide can be published so that newcomers to IDEX will not have a hard time using the site.

its decentralized more safe than your online exchange lol, its for people who really understands blockchain not for likes of below average traders

I think IDEX is more successful than Etherdelta. Our expectation from IDEX is very high.
Despite everything I prefer IDEX because it is more useful than other markets.

you are an idiot, people who were hacked in the ED incident was fooled by sending their keys to the fake website.. do your research its not for you who dont understand the blockchain

Yeah, you're quite right. A week ago I thought about opening an account with IDEX, but didn't do yet. Having read this topic, maybe I should give a second thought. Non-technique guys need a user-friendly interface and functions, be the exchange centralized or decentralize platform.

Bunch of idiots right here. Spreading about miss false condition about idex exchange site. But you can see that all of the things are running smoothly right now.
You are quoting who don't even know about the truth. He can be considered as created another spam post.
I'm using mew and never get any problem.

The users that have already redirected to the fake site.

IoIz... I had such experience with IDEX, I think they need to improve on their user interface for them to get more volume, IDEX is a good place to trade tokens when they are not yet listed.

After the experienced I had with IDEX I think its two months ago where when I sold one of my tokens there, I received less of what I should be receiving and they are not showing how much you will get if you put your sell order there. When I look at other exchanges, they are showing how much I will receive upon selling. Later on I figured out what happened and its because they are on maintenance that day and they didn't even put an update in their site. I am avoiding this exchange as much as possible.

What a complicated system there, that users find it hard to work on this site, also came across this!

If you want to stay away from IDEX exchange do what you want, because there are many great exchanges site. The most popular exchange is bittrex, poloniex, binance kucoin etc.  that may used to trade your coins. And if you think are IDEX are bad there are many options that you may choose.

indeed sometimes we are made difficult in sending our tokens there, because the volume there is very large, so we are likely to experience pending. but I like it because it's complete with new coin

I agreed with OP, Idex is kind of confusing to use for the first time. Fees wise is slightly expensive than centralised exchange which is still alright IMO. However, the website is really slow and lag on mobile devices, this is the main reason that is stopping me from reading there.

My opinion IDEX is a good decentralized exchanger! I think that soon enough good coins will appear on the coins! The interface is good, intuitive! I do not understand why he does not like someone!

I will also sell tokens at IDEX but fitting I see the cost for his deposit is huge, then I cancel to sell it on IDEX.

almost the same as the HitBTC who charge very high. Oh My God!

if IDEX and HitBTC like that continue then I think the Exchange is less in the interest by investors and will be unable to compete with other Exchange

I haven't tried Idex but I read that you need to enter your private key here with the help of Metamask, they are quite different but I hope there is a room for improvement for this exchange, it's the easiest way to get your token here because the application is not that hard to compare to other big exchanges.

It's a decentralized exchange and having some issues with it is completely normal. Guys, it's a new technology and underlying layer is not mature enough yet to build something on top.
Always it is nice to remember, you are in a new technology and one of the first users of it.
Patient.

This is the issue with most of the dexes , IDEX is at least more user friendly when comparing with Other dexes like etherdelta .DEXEs ned to be user friendly and need to move for cross-chain if they need to reach the huge volume of centralized exchanges.

FEES are a RIP OFF for sure. But their main argument is that users are responsible for covering all gas fees required to use the exchange in addition to the exchange fees. Trades on IDEX cost ~140k gas and this is too much. But hopefully we will be able to use Stellar's exchange soon.

I thought it's only me that sees idex as a shit exchange. You can't trade freely like other exchanges. The most annoying part now is the fact that there is an exchange limit which doesn't profit small traders.

yes idex was quite worst dex. dex with minimal amount of token if you want to put sell order. it's quite funny since it was dex. i understand if centralized got minimum sell order amount. but when it comes dex it's quite funny

I've been using IDEX for quite a while and i don't encounter any problem with it. It is just like much the same as Hitbtc when transferring token to their site and don't need an expert to do that.

IDEX is a de-centralized exchange. Now de-centralized exchanges aren't the mainstream, but in the future there may be more people using these types of exchanges, and it's safer to use them so that you can keep your own purse without having to transfer coins to the exchange.

I have large experience of using IDEX and for me it is far better than ether delta. I faced several times problem with withdrawal due to maintenance on web site, but support was quite responsive.
I don't like about idex 2 things: centralization while they claim to be decentralized and 0.15 ETH minimum transaction

If you open IDEX through metamask there is no need to enter your private key anymore. There are options on how to create an account on IDEX and one of them is the importation of private key which i did one time and got no problem with it. Just make sure that the site you are entering is not a phishing site because that's where the problem starts.

I understand that you mean it's true that the market idea is bad for deposits and also witdraw trading all require fees and also for newly registered altcoins the prices are very cheap and even lower than ico, I'm also disappointed with the trading rules where the minimum is 0.05 ethreum we can only sell it if it is below 0.05 it can't.

What? I never had any problem with IDEX. And I do not understand what are you trying to do? Simply, login with metamask, click on deposit Ethereum in my balance section, wait and trade :).

  I always used IDEX and i did not encounter any problem or issues using it. Actually IDEX is much better to use than Etherdelta and it is easy to use. You should learn very well how to make deposit and withdrawal and of course it need your patience. But based on my experienced i deposit and make withdrawal very fast. Well it is just my experienced using IDEX until now. For me IDEX is a good decentralized exchange.

Except for the minimum take and make order, IDEX just work perfectly fine for me. Trading and withdrawing tokens from IDEX is less hassle than those of centralized exchange.

Agreed. Just be more vigilant, as there are phishing sites that many come across. IDEX is quite a convenient exchange but it is not the best. Just to IDEX, you can buy tokens which are not on other exchanges.

i also have the same experience and its so irritated,i remember when i remember my trade in that exchange oh i really feel so bad.and you right etherdelta is better than idex.

IDEX and other ethereum based DEXs are useful for newly created tokens that can't get on a proper exchange. They have to trade somewhere and forkdelta is a cheap place to list. IDEX is supposed to be an improved version but none offer the simplicity of a regular exchange like kucoin

Haven't used idex before. I am just not comfortable syncing my eth wallet with any extention. That why I have stay away from decentralized exchanges thus far

Idex may be bad but when compared to Etherdelta or even Forkdelta, it's still way better to use it

As per my personal experience my only problem with idex is it response very slow or the right term is it lags really bad that I thought I had my sell order cancelled but upon checking a few days after my token was already sold. I intend to change the price for my sell order coz I had it set for quite cheaper but it was gone at once. And also its minimum trade should at least be change to a little lower value like 0.05 eth instead of 0.15 eth as I have some few altcoins from my bounty reward that I could not sell with idex because it wouldn't reach the required minimum trade there.

Oh man, sorry to hear that, just only now that i knew that this exchange is way better than forkdelta, thanks for this information by the way, i would definitely find another exchange which is better than IDEX, i have some tokens which i am planning to sell in the exchanges, so that is why im searching for the best exchange.

Thanks and goodluck

IDEX is a bad market, are you serious?
it seems you have to be more patient. because idex is a decentralized market so it takes time when you want to order, deposit or withdraw. I think Idex is better than ether or forkdelta. maybe for new users a little difficult.

To be honest Idex has been good and functional for me for atleast last few months, i know they had bugs and stability issues initially but they seem to have come up with a smooth exchange now, good work by their team.

Yes this exchange keep on maintenance thats why  traders dont want to trade and looking for another option hopefully IDEX team will  fix this

I will say a few things to the IDEX exchange. This is a security vulnerability that everyone has raised. Numerous people are being hacked by IDEX. And IDEX does not make any excuses.
This exchange is very uncomfortable even for trading because the amount of each coin is too small.
I urge novices to never trade in IDEX.

I really like these exchange comfortable to translate the tokens, and the speed was good !

Etherdelta is the worst exchange I have ever used. I lost more than 2ETH when this exchange was hacked and its interface caused me discomfort. Idex is the same but it is better secured. In short, I exchange  etherdelta and Idex

I don't see any problem with IDEX, may some delays only it happens sometimes especially when there is exchange maintenance and market traffic.  We also consider that certain scenarios and we can be experienced it also in other exchange sites.

This is nonsense. You can't get hacked by IDEX or getting hacked on their exchange because you, and you alone, control your own personal wallet (with its private key and funds), which you use to trade on IDEX. They can't trade, deposit or withdraw your funds without your cryptographic signature. If any kind of 'hack' happened to 'numerous' users, it is their own fault.

okay it is not the best but i dont think that it is so bad. i have been using it for so long time. i haven't had any real problems on idex exchanges. and idex platform is very useful to collect before listing in a big exchange.

Yes, had some simillar experiences like you did. Full of bugs , volume is almost dead everytime visiting. Fees are only thing maybe that is looking okay like some other discent exchange have.
I really do not get why would someone go thereespecially for the first exchange. Really strange decisions people make.

I do not think that the problem is in the stock exchange, because personally I use it very often, it does provide opportunities for trading, but not for bots who constantly interrupt their positions, it is for them that the exchange is not very good, because gas is constantly burned, this expensive.

It's not as bad as you assure. I'm coming in idex through a private key and no problems arise. The only thing I do not like is that it is not possible to place a order to a small number of tokens.

idex is not too bad because idex is a dex exchange that has a decent volume compared to others and does not often experience problems like other dex exchange but there is a slight disadvantage that their maker / tarker sometimes ups and downs does not always remain

dude, i think you dont know how to use idex, as long as i trade there, no erross, or something like you said.
i think you should read the rule before trade, and not judge before know the true, that describe how stupid you are.

Agreed, IDEX's platform is somewhat complicated. maybe an
web design upgrade would be a great idea, tagging @IDEX

Yeah, I don`t have any problems with IDEX too. The only problem is that you can`t trade there with a small number of your coins, sometimes it is annoying.

I have been using Idex for a while but so far it's fine by me. I have deposited, traded and withdrawal on Idex and so far it's okay. I hope it will smooth like I always do on Idex. That's my experience for Idex.

There are some people loosing their ethereum from idex account. If you aware about the latest case of idex and there was a lot of people were complaining about their amounts were disappear from their account. Maybe idex still has some bugs on its system that made the amount can't be displayed.

Every One hate Idex But the issue is that you get coin cheap as hell so basically is a way to instead of just going other exchanges

I read that this is the yobit of the ethereum based token, because it is so easy for token to get in here this is the hub od airdrops I have done one exchange here and they are good transfer to my wallet is fast, but this is not a popular exchange because they cater to ethereum based token.

You make a mistake by giving your opinion about Idex. Idex is a decentralized trading platform, I think idex is better and safer than etherdelta and forkdelta. because they are quite different but I hope there is room for improvement for this exchange, this is the easiest way to get your token here because the application is not too difficult compared to other big exchanges.

Yes, not the best exchange, it hangs up very much, but there are a lot of new coins and it is integrated with the purse of the etherium.

A DEx but require minimum order with 0.15 ETH equivalent value. And the minimum fee is the same, and many people get stuck in their tokens. One way people should notice.

I have used idex many times and i liked it. Well idex is definitely not as sophisticated as some other good exchanges. I still prefer it over most centralized exchanges that make use of bots in trading. Idex has real volume and it has real traders. I also like idex for the fact that it is a good place to buy coin cheaply, because some people believe they can dump their coins there. So, its an exchange with lots of opportunities.

I myself use this exchange. As for me, this is the best of all. I recommend it to everyone. It has tokens, which is very convenient and beneficial for everyone.

Idex is not a bad exchange... I think not everyone knows how to make use of the exchange have make use of idex exchange and I enjoyed using it.

I  used Idex many times and never had any difficulties. This is a good exchange. Once you've learned to use Etherdelta, you can easily use any of the decentralized exchange, including Idex. Deposits are recorded everywhere the same type.

I used Idex many times and i liked!Works well for me, obviously compared to etherdelta she is wonderful!but it really takes a while between actions and is not very intuitive.

I use the IDEX exchange for a long time and any problems never were. Sold tokens and bought without problems. I do not know in what at you there were problems.

Well different people will have different opinion and i would like to say that IDEX might be good for those who are familiar with it and it could turn out to be worst nightmare for newbies as IDEX is not user friendly in my opinion as i have rarely used it.

You can use IDEX by just importing your private key but just be careful that it is not a phishing site you are opening. IDEX and ED are just the same in terms of use but i prefer using IDEX because i am comfortable trading with it.

And I really like this decentralized exchange. I even got myself 1 IDEX token and now I don't pay for the commission

I have used IDEX and i have not encountered any problem with it and i don't know why you have transferring tokens from your wallet to IDEX since it does not take a genius to do it.

Withdrawal fee is a rip off for sure but Idex is not that bad. It is a decentralised exchange and your funds are more safer here than in any centralized exchange. I have not faced many problems there and it has been good experience to trade on Idex. Besides, you get to invest in many micro cap there which are not available anywhere else. With time, there will be improvements too.

Yeah you are so right on this. I have once tried using the exchange and I was faced by the worstuser experience. I need they gotta do better

Can you elaborate more on what problems you encountered using IDEX because i have been using IDEX and have no problem with it though i agree that the fees are a little bit high but as i can see they are adjusting it right now.

IDEX does not always give you the prices reasonable. prices there are even further from the value which should be owned and is certainly a lot to make owners of the coins sell at a price of panic for fear prices will increasingly fall. indeed always receive first but for this value is bad.

At first actually i have 0 experience trading in IDEX, but i ask my friend how to trade in IDEX. If you don't know about something, don't be hesitate to ask your friend or community, there will always crypto community in a country. It is better than do something that you don't know.

Perhaps due to the service is decentralized so  information or guidance about the service is very limited, however I see some people here have a good experience with Idex and not facing any problems. A decentralized exchange might be a little bit hard to use it rather than using centralized exchange but at least your fund is safe, you just need to learn properly how to use it. I Haven't used IDEX before I personally will wait for my tokens hit the big exchange I mean centralized exchange.

This is not an ideal exchange. But it is working. If you understand all the details everything becomes clear

I think IDEX is a more convenient decentralized crypto exchange than all the others. I figured out all the functionality in just a few minutes. EtherDelta and ForkDelta are much worse in my opinion.

If you don't like the price of your token upon listing on IDEX you always have the option of not to sell it and hold it until the price increased. It is not IDEX that dictate the price i think. It is always the demand and supply that dictate it.

been using it for quite some time now , never had encounter some error. Maybe sometimes your internet connection sometime affects some issue when trading there, its a matter of choice though. I prefer idex than etherdelta.

I hate that exchange basically because it has led to the death of many a promising projects and coins. They just list coin without the sole permission of the Dev and team. So bad!

No,  etherdelata and forkdelta are still good exchanges only the most concerned is that of its low volume and prices compared to others.
Etherdelata give me knowledge on trading as this is my first exchanges, and I'm comfortable doing it.

I have been using IDEX for some time now along with a lot of my friends and I have not encountered these problems you guys are talking about. Although I have had some issues with confirmation of deposits during the time of the whole crypto kitties issue. But IDEX has been good so far for me. Its even better than a lot of centralized exchanges.

I think you properly not known about idex, idex not give you proper value of tokens it's always trying to how can it make fool you! this is my real experience.

generally do not understand what problems you all write.
Absolutely normal decentralized exchange with fairly quick entry and exit, in contrast to centralized exchanges.
Yes, not all at once is clear - so sort out.
I, without the knowledge of English, took about 40 minutes to figure it out.
Since then I successfully use.

IDEX is very horrified to trade.
I'd better hold my token without having to sell it there.

IDEX is full of CHEAT, I strongly do not recommend playing there.

But they have very less fees also no withdrawal fees only gas fees are required. I know Idex have comparatively less volume but I like Idex...  ;D

I have known that for a long time, so I have never used Idex to withdraw and deposit. I only use etherdelta or forkdelta.

I think IDEX is not suitable for everyone, it makes people feel very uncomfortable. Due to the large number of users, the trouble of using IDEX switches is constant, so I almost don't need it now.

I have used the IDEX with no issues.  Looks like I may be lucky.  I did have my funds stuck on there for 24 hrs when the site went down however it all worked out in the end.  I would use it in a pinch but not for full time trading.  

I had my money stuck on there for a week when it went down.  I was freaking the hell out.  Everything turned out fine and I have since began using it again however I am always a bit nervous.  I had no issues with Fork Delta however. 

thank you for telling your experience, I will be careful, yesterday I just sold BOB tokens on IDEX but nothing bad happened.

I think it is an upgraded version of etherdelta, where you have the opportunity to buy cheap token and earn a terrible profit. One thing I do not like about Idex is that min trade and min withdraw are  high.

I tried IDEX. But there are several issues that makes me feel the platform is unreliable, so I finally gave up. Now I use Forkdelta and JOYSO. I use Forkdelta because it was my first DEX and JOYSO is smooth and secure.

why do you comment badly about idex, I often trade on IDEX and it's very easy to get on WD and I never get a significant problem on IDEX exchangers

Maybe you guys are the lucky and I'm not :P

IDEX exchange with a very expensive fee. I first used Idex and didn't want to use it again. etherdelta and forkdelta are better, but the network is very slow.

Except for the minimum take and make order, IDEX just work perfectly fine for me. Trading and withdrawing tokens from IDEX is less hassle than those of centralized exchange.

I agree with you . Previously I used IDEX once and found the inconvenience and disability of this exchange compared to other exchange. Nowadays, I mainly use: Huobi, Coinex, Kucoin

until now I often use IDEX and there have never been any problems.
clearly IDEX in my opinion is good, and new coins are now mostly registered on IDEX.

There are lots of people encountered negative on IDEX. Though I do not encounter or I do not yet use IDEX but as far as I know and heared from others I will not use it.

Their is no doubt that idex lags but I must say that u gave not had any significant bad experience with idex though in my opinion. Its pretty easy to use idex if you master how to use it but the bottom line is, it needs improvement though

I don't understand what people are complaining about. Figuring out how to use IDEX is not that difficult. I find centralised exchanges a much bigger pain in the ass. Especially all the repeated security checks they ask you to do because they are more vulnerable to being hacked. Simple fact is DEX's are much safer and more in keeping with the decentralised philosophy of cryptocurrency. You don't want the government or the big banks to control your money but you hand that control to an exchange owner? Makes no sense.

I do not understand what you do not like IDEX, but personally my opinion is that it is much better and faster than Etherdelta or ForkDelta. Of course, in this exchange there are advantages and disadvantages (like all the others), but I do not have problems with it.

IDEX has always been first in terms of accepting the crypto. However, there are also weaknesses in the IDEX where the value does not always match expectations. very much even it is not predictable from the ICO that value should be. maybe don't expect much if you've entered in IDEX. just wait to get into another big market that at least could lift its value.

I haven't used Idex before, for ERC20 token trading i only use ForkDelta and EtherDelta. Thank you OP, after reading your thread i decide never using Idex.

Personally, I haven't experienced any technical problem while using IDEX. But, honestly, I hate about their fees. I can't sell my tokens if the amount is little. Because IDEX has minimum selling fees.

I have also been using IDEX for a quite time and I have no bad experience to that exchange. In fact that exchange I trusted most. Because of its transparency. Try contacting the support team, maybe they can help regarding your concern.

For me this exchange one of the best on it trades almost all currency pairs a huge plus is that I can pull any coin from my wallet directly to this exchange without using any additional exchange.

Never heard that JOYSO, is this decentralized too?

You can also use ethernext it's more likely forkdelta and ED with the same interface. Just rarely use idex because it needed to connect with metamask which unfortunately I don't have. Maybe I'll just use this when it's really necessary for me.

never heard of decentralize exchange that has been mentioned above but i do only use etherdelta when it comes to exchanging alts and tokens . i think etherdelta is the best because it is only the first decentralize exchange that accept almost all types of coins .

 all those other exchange that have been mentioned above are only a copy paste . you should guys trust only the original because the original is already been proven and tested for decades .

i dont understand why people love to use unkown exchanges other than the famous and popular ones .

Maybe when you use Idex, it was erroring. Same with etherdelta that always error also. In etherdelta there is withdrawal fee also but I think IDEX is slightly better than etherdelta, morever if seen from the trading volume and the same coin usually the price tends to be higher in IDEX compared to the price in etherdelta, good service, the transaction is always smooth altough there is limit minimum when trading and withdrawing. But so far I have never got a problem on IDEX and hopefully never.

Better to take some english course, i hardly to understand your post. There is no such thing like "erroring" in english.
IDEX is indeed better than Etherdelta, but it's still far if you compare with Binance and bittrex. I wouldn't use IDEX or etherdelta because there is no reason to sell on exchange site like that.

Its a decentralized exchange and it's pretty legit as in I haven't seen any major complains about it yet, other than the usual nitpicks. You have to understand they're pretty new to the game. I haven't used it thoroughly though, regardless do not store any coins in any exchange no matter how legit they seem.

I was very disappointed when several bounty reward tokens had to be listed on IDEX because I didn't like the fee withdraw there which was very expensive

idex is cool it's just that you have to learn how to use it,  or else you might get burnt,  if u don't know how to use idex you are really missing out

Apparently IDEX is much better forkdelta. I also like to use IDEX to buy the cheap token before it is listed at the larger exchange. I just do not like IDEX at some point as the fees are quite expensive and the interface is difficult to use for beginners

I have never had any problems with IDEX exchange to be honest.
I still like Forkdelta more tho

I'm still using IDEX for trading my token received from bounty campaign. It work great with me without any problem. I'm tried to use EtherDelta but since it not list my token there so I have to use IDEX and it work great with me.

IDEX is legit because this is the best DEX exchange on market right now I think. Maybe this is not so simple to make an exchange there if we mean usability but they have a lot of altcoins and also you can use Metamask for trades. I usually do that. After Etherdelta I don't use private keys. This is not very convenient  market place if you trade les than 0.1 eth . So don't try to trade there with low deposit.

Idex is only for traders with large capital, but that does not mean bad.
idex has good services like forkdelta and etherdelta. besides that the number of withdrawl is also limited, this part becomes the most difficult and annoying thing.

You should know that most of this decentralized exchange are the same and there are dumping ground for new projects and bounty hunters. I do save my earning and investment until there are listed in popular exchange.

I think IDEX is much more successful and safe than other DEX platforms, according to a decentralized exchange is fine at the moment

Yes, JOYSO is also a decentralized exchange but still not well-known. My personal experience is that it is fast and can save more gas fee. I think the volume on it is the only issue.
