Now, you can exchange crypto on any chain without connecting your wallet!

BSC to ETH, BTC to ETH - almost every chain.

So I have become changeNOW official partner (lowest Fee), and I’m using their API.
NO KYC is needed.

Could you share your thoughts with me?


PNNV.com


[To be implemented soon]

- Favicon ICON will be updated after i design the right one (a matter of hours) - DONE
- Dark Mode - for those who prefer a dark theme - DONE
- Option to share link with custom BTC amount - DONE


[08/24/2022]

- Added Night mode!
- Added Share button!

[08/23/2022]

- Favicon has been added.
- SSL has been implemented.

Few suggestion,
1. Please use HTTPS.
2. Add satoshi unit.

Kudos for the domain name and the project, i need an easy to use AND easy to remember source that gives me a weighted average (and i need it multiple times per day).

I agree with ETFbitcoin: we (I) need the satoshi unit, even more than the other units you have listed.

I started playing with the sources and switching between USD and EUR... Suddenly i ended up in a situation where 1 BTC was exactly 20.000 USD, and exactly 20.000 euro... And the only thing i could do to "fix" the issue was refreshing the complete page.. Is 20.000 EUR-USD/BTC some kind of default value you hard coded in case something goes wrong?
https://i.imgur.com/lS8qpRX.png

Also, it seems like the anchors at the bottom (for example: Bitcoin to gold) are missing... Maybe delete them?

Good effort, but you rushed to make the domain online before you were sure anything was working properly, which gave a negative definition of your service.

 - The site is giving the wrong bitcoin price.
 - can't go beyond three decimal places.
 - There is no night mode.
 - The site does not give results for numbers such as one dollars.

HTTPS is already been implemented.

You may confirm it via: https://pnnv.com/

Confirmed. But my browser didn't get forwarded there from pnnv.com, so that's something to add.

I also see the 1 BTC = 20,000 USD value, and refreshing doesn't correct it.

Hey!

Satoshi unit will be added shoertly!


Noted will be take cared. My developer told me he already fixed the problem with the 20K default.

It should be fixed by now. kindly confirm, it's always a pleasure to see you around.

Https-forward works now, but the Bitcoin price is still stuck at 20k.

Could you please try to clear cache and restart? It seems i can't recreate the problem.

Great initiative, agentF.  Even if Preev comes back online, it's good to have and alternative option.  Especially one with SSL enabled.

I'm not a web developer, so this may be a silly question but I'm curious why are you using Java?

I use Tor browser in Private Browsing mode, so there is no cache.

Hey DireWolfM14,

Thanks for your reply!

Personally, I'm not a developer as well, I'm running a company with many developers (around 80 different developers)

The official developer response is:

"we are not using java, primarily since java cannot run on the browser.
 we are using react-js and the application does not have a backend at all"

Hope that it make sense to you mate!

---

Oh yes!

I see the problem on TOR let me ask my developer to fix it!

I cleared cache, used different web browser and price is always the same 20,000 USD, so it's most likely problem from your side.
I see in settings there is option to select Binance and Bitstamp and they are both unchecked, but if I select them nothing changes.
What default API sources are you exactly using to get correct up to date Bitcoin price?

PS
There is alternative made by other forum member examplens, and it works fine with coingecko api:
https://preev.net/

It's been tested on Safari, Chrome, Firefox it's all working well except for TOR.
I directly connect with binance and bitstamp with API - my developer will add much more resources.

As for preev.net, I wish him all the best you're free to use anything you like!

1. Your website looks pretty much exactly like preev did. While I don't mind, you may run into copyright issues.
2. After it ran well for a first look, no matter what I do (closed tab and opened new one), I see only 20k price. Firefox.

Good luck!

I tried few different browsers on different devices and in all cases I got $20k price. It can't be caching issue. Chrome on mobile, Firefox on PC.
And as said above, night mode for such kind of websites is must have thing. And domain is short, but maybe not easiest to remember.
Very similar, but not exactly same. Copyrights is tricky thing sometimes, but in this case, I doubt that OP may get problems.

Seems like Bitstamp's API request keeps failing (due to CORS?), which is why the price gets stuck in the $20k.


Eventually, it goes through and the price shows up correctly.

I checked the website and had the same issue with the $20k and as mentioned, the value was fixed after refreshing the page but it is still confusing since the value turned later to $20k again.
First impressions, the site is simple and should be easy to remember, I prefer to see some major altcoins too.
Keep up the good work :)

Kudos to you for the effort, however, it doesn't seem to be working properly. As others have already mentioned, it's showing the wrong price, at $20.000. As you've already mentioned, your developer is already working on it, but that's not my main concern.

The conversion from dollars to BTC isn't working. For instance, if I want to see how much Bitcoin I can get for $100, it displays nothing. I didn't see any of the previous posters mentioning it.

The domain is short indeed, but the lettering is a bit confusing. Everyone was used to Preev.com, examplens' Preev.net domain is almost identical to the original.

Edit: Tried again, always in incognito of course, and the price after a few attempts is displaying correctly. However, I can't seem to able to type any decimals, such as 0.08 BTC.

Hey the more the merrier! Your site doesn't work for me at the moment though?

I made my own preev.com alternative when it recently started becoming unreliable, originally posted it in collectibles and just posted here yesterday.

https://bitcointalk.org/index.php?topic=5410693.0

Once you iron the bugs out, feel free to use my key-less api as a backup weighted price source if you'd like  :D

It seems that I was able to access preev with this price:

https://i.imgur.com/Owj7ZMR.png

But probably in my local cache though,  :D because the price is not updated.

However, when I try to access to access https://pnnv.com/ right now, it seems to be down? Anyone experiencing the same issue or it is just me? (I also tested it to other browsers).

https://i.imgur.com/S5imy69.png

The price works now :) But the number of decimals needs some work.

Example:
I type: 0.258 BTC
I get 5,541.488399999999 USD (too many decimals).

I type 25 USD
I get 0.001 BTC (not enough decimals).

Yes mate!

Working on that as well, thank you for checking up again!

Great :) Have yourself an avatar!

(I've been waiting for an excuse to bump you up to Full Member)

The site is now working, there is still some delay but when I press the reset button everything is working fine.
Unfortunately the price does not change when I change units from K,BTC,m,u So I think you need some adjustments.
In general, it is good that there are no ads, but I wonder why you chose Pnnv.com?

Thank you LoyceV!


The delays will be fixed shortly!
Also, the units fix.

My website won't have any ads, as I have kids in a few years and i want to be part of history.

As for why I chose Pnnv.com, my first intentions were to buy preev.com; I offered a generous amount to the owner. Unfortunately, he is not responding. then, i was trying to buy preev.net, and I offered 5K to the current owner, but he didn't reply for a few days, so I decided to buy a four letters domain that will be easy to remember. It cost me a good amount of money to purchase the domain, and after I bought it, ironically, the owner of preev.net wanted to sell me the domain, but it was a little too late.

Yes, will tell my developer to force everyone to use the https via the httaccess to

It's working fine now and showing correct btc value, but you may want to use some fallback API server in case default one is not working correctly due to some policies from Bitstamp.
Using single exchange is fine but I prefer having middle value of multiple reliable exchanges with high volume, something like aggregator value.

Hey !

UPDATE:

Added Night mode!
Added Share button!

I just played with it a bit, and the site is looking good.  I like the night mode feature, cool addition.  I'm sure it's still a work in progress but I did find an issue that you may want to resolve; I found that it doesn't convert backwards from fiat to BTC, i.e. if I want to see how much bitcoin is equivalent to $500 USD (or any fiat) the BTC field is stuck at "1". 

Changing the fiat amount doesn't change the BTC amount:
https://i.postimg.cc/nrXxb9yf/image.png

All the updates that have been done are excellent, the site looks beautiful and I liked the night mode, you may need to modify the code because when I type a price in dollars I cannot know the equivalent value of bitcoin, and there is no way to reverse the place of bitcoin with the dollar and vice versa.

Overall, thanks for the quick and continuous update. I hope there will be a lot of visits.

Oh thank you for that, valuable friend!
Working to fix it shortly!


Thank you for your valuable feedback!
I will fix that shortly!

Updating you that i have fixed this bug!
Thanks for letting me know

This happened to me when I was using default USD or EUR currencies after selecting both exchanges Bitstamp and Binance, so rounding should be fixed in this case also.
Dark mode looks cool, and I would update old logo from PREEV to PNNV, it doesn't have to be anything special or fancy.

This has been fixed!

The site really like preev.

I don't know what has been fixed as mentioned on the quoted posts but these two below is i can still experienced.
-The conversion when changing from USD to EUR.
-Also the rounding off of the decimals to at least 2 decimals.

Overall it's good as preev, nothing to add though since im not that fan of using preev. But i appreciate as others do usually use preev.

Hi AgentF, I read the last post about your plans to run an avatar campaign. Idk whether your website already has a logo or not, but I don't think so.
Since your web is non-profit for now and I have an overnight free ;D, I created something that might work for your next campaign. Choose one:

https://i.imgur.com/7j4nMZ2.png https://i.imgur.com/aMeG30K.png
Consider this a reward for your kindness, you've ever paid me more for 1 job (surely you don't remember it do you?).
Don't hesitate to use it and good luck for your web ;)

came here from the another thread where OP mentioned his domain and thread. and just wanted to post it to encourage OP to contineu his good work. it is really a good backup altertnaive of preev.
and also want to suggest OP to place some banner ads in his website so you can make some profit to keep your website active..

Thank you for your contribution, and I remember you, my dear friend.
I will gladly use your avatar.


Thank you, my site won't have any ADS placement; I'm blessed and will keep the website alive for at least 20 years.

As a non-native English speaker, I have to ask: how do you pronounce PNNV?

I wish I knew, I was looking for a short and easy-to-remember domain :)
BTW the ANN thread has been designed and updated on the first page!

Personally i pronounce it as P- N - V  ;D  

Also stay tuned as a bounty campaign which will be posted later today.

I still don't know what does preev means and now I have another one 😉
What does pnnv means or it just to carry on with the preev trend.

Did you have it in mind https://abbreviations.woxikon.com/en/pnnv

Hell of a work you have done there. Good try brother. I hope pnnv becomes a brand like preev.

I must say that the ANN thread title is not so good with the words like "Preev is down", so we have PNNV. Forget about the preev.com, PNNV has an identity and place and you shouldn't be caring even if any day Preev.com come back. You can develop a better site than that one.

Secondly, i just read all the previous posts here on this thread and am happy to see you take feedback from the people and try to fix it then and there. Introducing the avator campaign will help you grow immensely.

Thank you for your kind words!

Trying to create my own brand i even trying to change the design but of course to keep it simple.

@agentF

None of the sites provides a correct value of bitcoin price in my local currency (BDT). According to PNNV, the price is BDT ~1900000 while the actual market price is BDT ~230000. There's a gap of BDT 400k which is almost $3.5k. The USD rate you are using is most possibly the rate we can see in google. While in Binance it has almost a gap of BDT 20. I hope I was able to make it clear. If possible, use Binance p2p rate for providing the data. That's the market price in our country.

Can you design a set of signature? That would be helpful for you because there are some good guys here not having any signature but would definitely love to promote a non profit platform like pnnv.com.

Hey Little Mouse!

Thank you for your valuable feedback!

In my Server BackEND, I'm using 4-5 different APIs and making an average between them. I have updated my DEV regarding your request. He'll fix this shortly.

I would definitely design a signature; however, not sure if anyone wore it for free!

As for my project, I was thinking of forcing the dark mode by default. What do you think?

I'm in a campaign now. If I were not in any campaign, I would gladly wear your signature as appreciation of your effort for this project. You know there are some people who don't think want to promote anything on their sig but would gladly promote such a project.

I just have checked with dark mode and it's looking good. Will you have the light mode as option or that will be taken down? If both available and dark mode by default is set, I see no problem. But having the legacy of preev.com, I would prefer the light as by default, same as preev had.

Yes, people will not wear signatures for free and even those who will wear won't be active much in the forum and they will let go as soon as they are accepted in any campaign.
The better option would be to start the paid signature campaign for your site once the Avatar campaign ends. Also by that time, you will have a good idea of the outcome and results of the campaign.



I will prefer the Light mode. Anyways it's my choice and everyone would have their own choices. Giving a toggle button at top of the site for light/dark mode is the most suitable option.

i just wondering will you add another cryptocurrency to your site just like Preev that has Doge and LTC


i think adding a signature to the current avatar campaign is better and you can just tell them to wear it if anyone wants to do it

I remember the question thread here (https://bitcointalk.org/index.php?topic=5407767.0).
If you check it, there are some members who seem to be willing to do your initiative with your site's notes only continue to serve Bitcoin calculations (maybe it's okay even though you add some altcoin). You should not need to be pessimistic anymore and immediately put the signatures design on the OP.

Hey Guys!

Signature  design has been added to my second post of this thread.

You underestimated this a bit as I see many of the avatar campaign participants are wearing the signature too.
Even i am wearing it as it looks cool.  :)

Some time back I was really missing preev.com but I was so glad once I found out that https://pnnv.com/ is providing the same service and a very clean interface.

I was using Pnnv site since weeks now and it is doing what it was supposed to do to replace preev. The only exception is that pnnv offers more FIAT to convert BTC to, but it doesn't have litecoin and dogecoin which I still find interesting to take a look to.
Is there a plan to add some major cryptocurrencies in the future? (I suggested that in a previous post).
Good work op

By the end of the weekend, im planning a major update with many crypto currencies support!

I have made updates!

- You can now search any token as long as it listed on CoinMarketCap or CoinGecko.
- You can see the price on the TAB.

You can read all about it here:

https://bitcointalk.org/index.php?topic=5414024.new#new

http://preev.com is up! Now what? Continue PNNV.com development to replace Preev.com or do something different?

It takes much time to load the site so not sure if it is working or not..
At this point and with the recurrent issues with preev.com, I will stick with pnnv.com which is better, have more options and of course up and running!

It's up now now, but there is no guarantees that it wont go down again after month or two. I think it would be good to continue development of new websites. And it's always good to have an alternative.

Statistics:

https://i.imgur.com/6aXxpsO.png

It is nice to see such good statistics after a short period of time ;)
I am visiting the site twice a day on average since the start and I almost forgot about preev.com..
I am not very engaged in discussion out of the forums and rarely visiting other alternatives but did you advertised your site on reddit? or other famous blogs/sites?

Statistics:

https://www.similarweb.com/website/pnnv.com/#overview

Was the avatar campaign worth it or was it a waste of money? Some of us have stopped wearing the avatar  ;D once u stop making payments  :-X.
Are you planning to continue investing in the site or is it just a side project as Preev.

Excuse me?

Did I stop making payments?

All the payments have been paid. im upgrading my website daily.
I have zero debts to anyone in this forum.


Once i will finish upgrade my website i might continue the avatar campaign, it didn't bring me so much traffic.

You misunderstood me, my question about the effect of stopping the advertising campaign on the statistics of visits, since the campaign stopped, some people stopped wearing the avatar, and was the campaign successful or is it not worth the payments?

Hello!

Is it ok when I choose two sources, the exchange rate doubles?
screenshot: https://prnt.sc/7OWbnfat0unz

I have checked and it actually is in my end. Now that's a bug which OP needs to fix, although he is in the process of updating/upgrading the site ^{(he mentioned (https://bitcointalk.org/index.php?topic=5410871.msg61078535#msg61078535))} i know he already aware of this specific problem so probably waiting is the only thing we can do at least for now.

It's something :) thanks!

Thank you for letting me know!

It's been fixed!

Honestly, when you first launched this website, it was barely functioning, and since then, I hadn't bothered to check for any progress. However, this quickly changed and the difference is day and night. You've featured the most popular coins along with the ability to search for any coin you're looking for, along with all fractions of it. The dark theme looks great too. All the information below the exchange rates ("About, Usage, etc.") is a great addition too.

The only thing I don't like, which is only a small minor detail, is the number of decimals. If I am to search for fractions of Bitcoin with a few decimals, the equivalent in USD includes way too many numbers and blows the whole thing out of proportion, making it look a little off. Personally, I'd limit them to two.

Apart from that tiny detail, you've done a great job. Congratulations!

https://i.ibb.co/crf10RV/pnnv.png (https://ibb.co/6W9mzGL)

Can you please change the title now preev is not anymore down, it has been up for a few days if I'm correct? It sounds misleading/unethical, to be honest with you. You are spending a lot of time, and money on the project and the result is great as far as I can see from the screenshot. Your project is an independent one now, it's of course good to remove the name of preev from your project.

Noted, it's been edited and removed.
Thank you for. your remarks.

Will be pushed on the next update!

I have a suggestion for the box that is shown for each coin displaying information such as market cap, 24 hour trading volume, supply, etc.

For each asset, you mention five exchanges. More precisely, you show five logos of five different exchanges. For those who have been around for some time, we can figure out which sites are mentioned as we recognize the logos, but newbies will struggle with that information. Can you make the pictures clickable and link to those particular platforms. At least you can add a text that appears with the name of the exchange when you hover your mouse over its logo.

Another question is about the exchanges. Based on what criteria did you decide which ones will be shown in the box? For example, you have Bibox for Bitcoin. But if I select Solana or Ethereum, Bibox doesn't appear in the box, but KuCoin and Binance does. Maybe a dropdown menu "More" next to the "Exchanges" field wouldn't be bad with links to other popular exchanges. 

Thank you for this project and I think it's currently the best from other available options that have recently popped up. I appreciate a lot the fact you don't use Cloudflare since I can access your site privately without any UX issues.

Thank you for that!


Yes, i already told my team to do so.
Will be pushed on the next update!


Thank you sir!

Now, you can exchange crypto on any chain without connecting your wallet!

BSC to ETH, BTC to ETH - almost every chain.

So I have become changeNOW official partner (lowest Fee), and I’m using their API.
NO KYC is needed.


Please check out: https://pnnv.com/exchange

Could you share your thoughts with me?

Are you 100% sure there will be NO KYC when using changeNOW exchange page on your website?
I know other services who are using the same exchange and people reported cases of customers getting coins frozen, than they needed to submit identification documents, and same thing is written on their website:
https://changenow.io/faq/kyc-aml-procedure

More information about this on kycnot.me website:
https://kycnot.me/exchange/changenow

Im 100% sure.

I use my own company, i receive the funds and use their API to change to the relevant token.
my company is KYC'ed.

As far as I know, it could be possible for certain transactions based on the amount. Up to €1000 or something if an individual or a business is located in the EU. However, the payment provider can ask you for additional info if it finds your transaction suspicious.
I mean, it would be cool to keep crypto payments in the No-KYC zone, but reality stands for the opposite.

Please read the recent update reviews here:


https://bitcointalk.org/index.php?topic=5427902.0

Won't that get you into trouble at some point? It will depend on where you are, but I've read stories about convictions for operating an unlicensed money transmitting business (https://www.justice.gov/usao-edny/pr/queens-man-convicted-laundering-bitcoin-and-operating-unlicensed-money-transmitting). Unless you're registered to do so, but in that case wouldn't you be the one to require KYC from your users?

Hey LoyceV,

Thanks for your reply, that's a really good questions.

So the way it works, it's pretty simple, changenow own the license for the exchange.

My company is KYC'ed with changenow, their license allows them to exchange crypto. you are correct at some point it might raise questions, however, im planning to switch to 1inch solution which is DEX.

I wouldn't say that 1inch is really a Dex exchange, and people won't be able to exchange and swap real Bitcoin but only tokens built on various centralized blockchains.
Maybe you could consider using atomic swaps instead, or use something that is connected with Bisq and other p2p trading platforms.

You don't have to be precise, but if it's not a secret can you tell us how much coins/money got exchanged using PNNV website through ChangeNow?

While I got excellent growth per month, I constantly working on my backlinks, working on keywords, and plenty of users on my live monitor - which I continuously improve.
Im working on creating my API instead of using others.

My exchange is not officially live yet, i got only a few exchanges made so far.

Can I make one suggestion that could improve your statistics, give you more exposure, and get more people using the exchange part of your website?
Maybe think about contacting kycnot.me website and see if they can review your website/exchange, rate it and list on their website.
There is already ChangeNow exchange listed with rating 7/10, but you are using different approach and you are not asking for any KYC.

Listing request page:
https://kycnot.me/generator?type=Exchange

I do not think it will raise questions, but what you are trying to present is closer to a money laundering service. It is better for you to hire or ask a legal advice office before continuing to provide such a service.

It may also lead to size your company and thus force you to disclose all user data and transfers that they have made, or they will force Changenow to do it, so in all cases you and the users may be harmed.

To avoid all of this, set the condition that KYC cannot be requested for transactions below $2,000.

I got you, im actually working on a better solution only it's not easy to find without the "connect wallet" option.

Your website seems to be a detailed version of the so-called preev.com, much better than it TBH so hats off for bringing it up.

However, even after being a mobile friendly website, I saw that it didn't update the price for around 2-3 minutes (I mean, it's not as "live" as it claims to be).
Is there any glitch or is there something wrong with my browser(s)? Tried this on Chrome and Brave browser, both have the same issue.

Just come here to read any update on PNNV and found this post. I never notice this glitch and if the price was delayed by two to three minutes, many more people would have complained about it.

I just checked both sites at the same time and got almost similar results.

Preev.com
https://i.imgur.com/EpemK1v.jpg

PNNV.com
https://i.imgur.com/1JGOSjT.jpg

I think they fix it now by checking Preev and PNVV they show almost the same results but between the two I prefer PNVV over Preev because Preev is blocked by my anti-virus and this is not good for the site's reputation.
I've been a long-time user of Preev but your site offers better security and a better interface and of course, they have very active support here which is good for a platform like this.

Yes,

Im constantly fixing the website!

furthermore, i got more than 310K monthly users.


https://i.imgur.com/B5kvdWM.png (https://pnnv.com/)

Could you add the "satoshis" denominator for Bitcoin? I've been using a wallet that ONLY shows my balance in satoshis, and while I understand their reasoning, it's honestly a pain in the ass to convert it to BTC units and then dollars all the time.

That's a huge achievement because your site is serving a huge community, this is the kind of tool that everyone needs I am a long-time user of Preev but now it's being an unsecured site makes it not worth visiting, I guess your timing to launch was good when Preev is offline, you filled the void during that time, and your early users stay on that is why you have a good flow of visitors.

Hey!

We do have a support for satoshis.

https://imgur.com/CexL3Ur

Oh, nice. From my experience a few years ago, some wallets used uBTC as a unit for 100 satoshis (0.000001 BTC), so I got confused. I should have tried first. :D

It is better to give an explanation of the smaller units of bitcoin so that it is not misleading.
Are there plans to make the code open source and thus help you in development and for everyone to host the site himself if any problem occurs.


There are some units smaller than the satoshi that we are beginning to see in the Lightning Network. The matter will be complicated in the future if the price of bitcoin exceeds 100K.

Yes!

Currently im working on my own API as it's not easy task to collect data from each exchange.
Different API's, but we are working on it.

Those aren't "sats", those are "bits". See Bitcoin Wiki (https://en.bitcoin.it/wiki/Satoshi_(unit)).

Thank you for that.

my bad, fixing.

PNNV.com live crypto monitor is a robust tool for monitoring the current exchange rate of cryptocurrencies. Monitor and swap your crypto now with PNNV.com

Does this mean PNNV.com will provide internal exchange?

Last time I checked there was exchange on PNNV.com that is using ChangeNow exchange service for this purpose:
https://pnnv.com/exchange
