Good work, I appreciate your effort to create this chrome extension tool.
I will try it and give my review after few days obviously, hopefully there is no problem about it.
This is totally safe, right? There is no any suspicious malware run in the background or activities being recorded? No offense, as I'm not an expert in this field of technology. And, do you have a plan to develop on other platforms such as facebook or telegram?

I am a skeptical person and prefer to be safe instead of take a risk, including the matter of browser extensions.
Have to chose what you are really need, very useful and developed by trusted third party.
Is it safe? Well, According to research due to be presented at the IEEE Symposium on Security and Privacy, the answer is not very. The Google-funded study found tens of millions of Chrome users have some variety of add-on based malware installed, which represents 5% of total Google traffic. http://www.makeuseof.com/tag/secure-chrome-web-store-anyway/, but as long as you can take a risk and know what you're doing, go ahead.

Nothing's free.Everything comes for a cause.
I'm against strange chrome extentions anyway because that is the simplest way to do various vulnerable activities or manipulate user data.The code should have been on github to verify the authenticity of the code.
I wouldn't advise installing the extension.

Yes, I agree with this.
I think this extension is very useful, but do not know what is in it if you do not expose the code from the extension. There could be malware. And from where the source took the movement of Bitcoin prices.
You should describe it clearly.

omg, one more price tracker. no sources, no everything
why are you doing this? what is a purpose of your work? how are you going to make money with it?

Hello All!
Thanks for your feedback. This is totally safe. It's just a small extension that gets prices from coin base and matches them with the rules that you set. Currently, it's not making any money for me. but ads will be the source of money in subsequent versions. I'm planning to add some more advanced rules for intelligent price tracking. You can view the product hunt page here. https://www.producthunt.com/posts/bitcoin-price-tracker (https://www.producthunt.com/posts/bitcoin-price-tracker)

As mentioned previously, I think posting the code to Github would be a good idea. Other developers have an easier time looking through your code without having to download / install it plus you the potential that another developer may take some time and add features for you.

Nice Idea! This is actually a good application for all bitcoin users, with it, we can track the value of bitcoin at any time. Updating the value of bitcoin soon will help me a lot. good luck!

thanks northstarh!

I totally understand that it's hard to trust an extension built by newbie on this forum. This extension has helped me catch the Bitcoin trends in the past. Its data source is from coinBase. When you install the extension, google chrome will notify you that `this extension can read/write your data on coinBase`. Although it doesn't `write` any data to coinBase, there is no way to tell google that the extension only reads data. You can confirm that by reading this article. https://blog.malwarebytes.com/threat-analysis/2016/01/rogue-google-chrome-extension-spies-on-you/ (https://blog.malwarebytes.com/threat-analysis/2016/01/rogue-google-chrome-extension-spies-on-you/)
My extension does not do any of those things. google chrome lists all the external servers that the extension can talk to before you install the extension. Anyone can verify that when you tap `add to chrome` This extension does not read/write data on the web page.

The source code of the extension can be accessed via `chrome developer tools` i think that is much better than GitHub because you are actually viewing the code that is run by chrome. I'm sure that you will agree with me after you inspect the chrome dev tools that this is a clean, simple and very useful extension.

It is currently free because it's just the 2nd version of the extension. I'm planning to add more features and ads /pro version of the extension.

Cheers!

Hello error08,
yes! it is completely safe. we have around 500+ users now. and some great feedback! We are planning to launch it on firefox and facebook messenger. Also there will be some new triggers to track crypto currency prices but they might not be free.

We will keep this thread updated as and when we add new features!. You can also visit our  product hunt page https://www.producthunt.com/posts/bitcoin-price-tracker (https://www.producthunt.com/posts/bitcoin-price-tracker)

Cheers!

Thank you! This is great idea! And very useful. Will use it for sure

Thanks! :) I purchased some bitcoins yesterday when the price dropped below 5100 AUD. now it's 5400 AUD again!

This is a good idea, however there is a high risk on my data's security since the chrome extension is not ecrypted at all, so i'm having a second thought if i should give it a try.

We can understand your concern. We will be releasing the next version of the extension under open source license. Hope that helps!

Very good job friend
I feel helpful for this.
And I hope soon you release the next version of the license under the open source license.
Let it not happen again to my concern.

You can also add a feature that will allow users to put their current bitcoin holding so that they can keep an eye on how much does they hold in bitcoin and changes in its value in last 24hour just like blockfolio app have.

Since chrome extensions are written in front-end (HTML, CSS, JS), I'm going to take a look inside and check for any malicious code, I'll post back the results when I'm done.

exactly! you can view the code in chrome dev tools. most of the logic is handled in background page. you can view its code by going to
cheers!

Right. Better safe than sorry.
If you want to track Bitcoin or ANY other cryptocurrency WITHOUT installing any third-party software or extensions try our web app called Alarmcoin (https://alarmco.in/). It is super useful and totally universal!

bitcoin price tracker is completely safe. no hidden code, no malware. You can confirm this by reading the javascript code in the extension.
