Show HN: I made a lightweight cryptocurrency price tracker

Hi Hacker News,

I'm Peter, founder of coinval.

So why coinval? There are hunderds of portfolio trackers out there. Unfortunately, I couldn't find a simple one that would be fast enough, had realtime prices and worked well on all devices. All I found seem to be extremely bloated.

It's been over a year since I use coinval both on mobile phone and PC. In Chrome (Windows) I always pin a tab with coinval and check current portfolio value regularly using a mouse cursor. During volatile trading days, I usually wait for my alerts to trigger. When there are big price movements, I just leave my phone on the table and watch relatime price movements. Thanks to sounds alerts I never missed any opportunity yet.

I've been tweaking coinval for over a year. Today, I finally decided to share this lightweight app with you, guys.

Please make sure you try all features, bookmark a customised URL (e.g. https://coinval.co/1250xlm/eur or https://coinval.co/eth) and share the app with your friends if you like it.

All the feedback is appreciated!

Cheers, Peter, founder

That's pretty cool Peter. Interesting how you did the storage and loginless/signinless account creation/state persistence.

Thanks for sharing.

Great job Peter !

I really appreciate the dark mode and the fact that I don't need to use an account to sign in.

Only thing that I didn't like is that I get a scientific format of the DOGE price on DOGEBTC pair. Only happens if I try to see the price of 1 DOGE, so it's not a big deal at all.

Thank you !

It looks nice and I'll definitely use it :). Just one thing I wanted to mention is that you append a new style element. If you switch a few times between light and dark you'll see a lot of style elements in the header.
