Topic: Bitcoin Calculator (Read 1139 times)

Just visit and try your site http://bitcoincalculator.co/ its good site but i need more crypto for calculation,now only for bitcoin i am using preev.com/ but most of the time i use https://coinmarketcap.com/calculator/. Its best to me,because i can use it for calculating all of crypto at once.try to make such kind of good service.peoples will be more attractive to your site.

Hello friends,
First of all, a big shout out to everyone who helped me by providing suggestions and feedbacks! Thank you so much!
As for now, I can safely say that a simple version of the calculator is ready.

For next version, I will add ability to add Newer currencies both crypto and fiat. I will keep posting updates.

Thanks again.

PS: here is the link http://bitcoincalculator.co, please check and provide feedbacks.

I see. Just visited the site again and wow it improved, looks better now. If we could calculate more or less than 1 cryptocurrency listed (like 2, 3 ... / 0.01, 0.5 ...), I think it would be okay to use already.

I have seen how this service works. There are still many basic shortcomings that I feel. If this service is trial and error it may not matter, but if you want to develop more broadly I think this is not enough. Try to note the coding you do, check again which is the problem. As a user of course I feel disappointed if not get the best features. Every function should be done with whatever nominal we input.

Nice and simple, I will start using this on my phone's browser. Thanks.

Actually, I use this calculator http://preev.com/ But I would use any, if there were as many kinds of tokens as possible

Can we not use the calculator yet? I see few options but no calculate button this would be nice I use google to do btc>usd it works fine not sure how accurate google is dedicated calculator would be nice I will definitely be using it gl with your project.

Your enthusiasm is great for this project and you can add EURO, GBP, etc . However if you want to convert any amount of btc to usd then you just need to type "1 BTC = USD" in your web browser and you can see what happens next . I would advise you to do something different .

1 quick question : Suppose I have a text file having some data . To understand the data type just think that you got some email ID(s) or phone numbers in comment section on any social media post, and you just copy pasted it into text file. Now I want to extract all set of phone numbers of that text file to another text file . Let me know which programming language will you use to do this ? If anyone wants to explain, please post a reply and send me the link to this post in inbox if possible .

which language you use for this calculator

I'm sorry...that's not the correct link! The correct link is http://bitcoincalculator.co ... I made an error typing the link. Thank you for your patience!!

It's really simple and does the job.
Adding as much crypto as well as fiat would help.
But I'm not being able to input the amount in the box. It's grayed out for me.

Oh you're using a new link? It says: This domain was recently registered at Namecheap. Please check back later!
I guess your site in this new domain isn't ready yet. Good luck anyway, your site could be a good alternative as well when preev has a problem in the future. Looking forward for more Local currencies.

No, you are right, it was not a connection problem. and yes, people were really helpful and i took their suggestions and implemented. thank you for your comment!!

p.s. link here http://bitcoincalculator.org

I took your suggestion and added the missing altcoins and other usual currencies. Thank you for your feedback!!

You are almost good to go for your currency converter but it is lacking of altering other usual currencies.
Kindly add Euro,GBP also to make it look like a good converter. Later you would have to bind altcoins like ether,litecoin

I couldn't see how it really works, it keeps on loading after clicking the button and not giving any result. I don't think it's a connection problem since I could stream online without a buff. Is it just me?

PS. A preev-like site would be good, leveled-up with altcoin would be better. You got pretty good suggestions from others so good luck.

Altcoin-bitcoin exchanges was also suggested previously by others. So, i guess this feature will somehow add some value to the application. I think I will take your suggestion to add other currencies like Euro, Pounds etc. Thank you very much. I appreciate your help!!

Well, at least you have tried to, appreciate your efforts. And simplicity is a good idea as the ultimate sophistication.
As there are a lot of bitcoin calculators, it's good to try add some features such as altcoins-bitcoin exchange rate and add more currencies such as Euro, Pounds, jpy and cny. But, I realize api expenses is an obstacle to develop further, hopefully you find a way to maximize your service.

Thank you for suggesting altcoin. Perhaps, it is better idea to include altcoin as well. The price is provided by BitcoinAveragae for now. I also have credited in the footer section of the site. May be i should put it on top somewhere for more visibility. Thanks again!!

Good start, I like your site, simple and easy to understand. Suggestions for converting to altcoin as well. For bitcoin prices on the site it refers to the price where?
I will wait for the latest announcement from you.

It is always good to encourage people on developing different tools, even if it already exist (preev.com), different providers are always good, and it is good for education and exercise purposes.

Good idea, but it would be better to request the convertion rate from the server instead of requesting infos from a provider on user side, just a side note.

I like the simple design 

send request when a user stopped typing. add setTimeout 1 second to onChange event for example.

About 7 years late, huh! Hilarious!!

A price ticker as image could be handy for some. Something like 1USD = BTC

You are right, but let he try.

Great idea, but you are late about 7 years with realisation of this idea. I think that such services already in place. I have this calculator in my Android bitcoin wallets for exmple

Adding more currencies is definitely a good idea. But about real time conversion, i omitted because i wanted to minimize api calls. But ultimately, real time data is the most required feature. I will find a way to minimize api expenses. ok. Thank you so much!

You are absolutely right. My script allowed digits but ignored decimal points. Thank you for pointing that out!

I really did not take notice of the average rate and possibility of fake rate. Thank you for your advice!

So this is only works for 1 Bitcoin or higher right? I've just tested your site and tried to input 0.1 or 2.1 Bitcoin but the result is " Not a valid amount" comparing to my favorite Bitcoin calculator over there you can check even for 1 Satoshi, sometimes people want to calculate a decimal amount since calculating decimal amount is kinda hard, just my suggestion it is better if your site can check decimal or amount that lower than 1 bitcoin.

OK! This is a good start and you can improve it of course.

Firstly, of all research if you can convert/calculate the bitcoin to usd and vise versa in real time without needing to touch the button to convert (like google)

Secondly, I would suggest to add more currencies and this would increase the complexity of the website which increase the productivity (like converting btc<=> eth <=> fiat)

Bitcoinaverage is fine if you want to give a global rate, you can use different rates from different exchanges and let the users choose. It would be interesting to do a cron job to get an update of the price every minute and use it instead of sending a query on user side.
You should know that using bitcoin average means that in the case someone dumps bitcoin on a low volume exchange, you will get a fake rate, you should use the exchanges directly, here is a small list :

I got it from coinmarketcap, you can also directly use them to get an average rate.

Regarding the features, maybe you can add different currencies and widgets.

Hi all!

I have just started to build a calculator that converts any amount of BTC to its equivalent price in USD. Also USD to BTC.
Like i said, i am just beginning to code this website, it only supports USD for now.
I need suggestions for which exchange currencies to add, just few important ones.
Also, since i am new to bitcoin, what other data is must necessary to be provided to end users.
I am studied few APIs, if you have any idea, I also need help to choose the best API.

The hyperlink is http://bitcoincalculator.co

I will post updates when available.


Thanks
