I created MyAltCoins to track all your cryptocurrency assets

[nommot]

Hm, I think I got it running now. Allthrough the amounts are incorrect. For example it shows CacheCoin which I don't own anymore since 2-3 weeks.

Is it safe to provide these API keys? What can the developer of this do with it?

The Cryptsy API is generally used to grab data from the markets, or from your personal account. This data is in the JSON format, and should be parsed using a script, so it's not really meant to be human readable just by pasting the URL in a browser.

It is not safe to leave your API keys in anyone else's hands for very long. A developer can use these keys to make orders, cancel orders, and even withdrawal coins to pre-approved addresses. So in theory, your coins could be maliciously stolen/traded if you have any pre-approved coin addresses, or by trading all the coins for cheap prices in small markets where the thief has placed coordinating orders on another account.

Personally, I do not think this developer would do such a thing. But, you should assume that this site will hacked eventually, and when it does, expect everything I explained above to happen.

Here's an easy solution to prevent this from happening while still using this useful site: Do not leave your Cryptsy API enabled when you aren't using it. I enable mine from the Cryptsy>Settings whenever I am using the Import function on MyAltCoins, and then I disable it once I'm done. If you feel like taking an extra precaution, generate a new API key after every time you use your keys on any site.

Can anyone confirm this? I've changed my API keys now. Only the iOS app 'Coin Ticker' has it now.

But, if a developer really can make trades with it, I might disable using API's.

This is great!  Could you add Pandacoin (PND)?  It's on the LTC market at Mintpal.
There are 3 Pandacoins, but this one (PND) is currently the best performing.  Ranked #80 on coinmarketcap.com

Thanks!

Don007, nommot is right about the security of the Api Keys. I leave mine on MyAltCoins since i trust the security of the servers. Many people trust me with their keys, and as i said multiple times, I will never use their api keys for personal gain. My name is easy to find from my username, and I stand behind MyAltCoins.

Of course I totally agree (and encourage) being a bit paranoid about your crypto assets.

NEW FEATURE: You can now export your transactions to Excel!

[Don007]

Alright, thanks for the (late) reply.

I didn't knew what people can do with API keys.. I'm going to be more defensive with those keys from now on (and removed the old ones). Thanks!

[lucacri]

No problem! We've all heard a lot of bad tales recently, your stance is more than justified.

I keep my api keys on the site because i trust it, but i totally understand if you don't

[lucacri]

New feature! Import your transactions from Kraken via Api!

Thanks for the heads up!

I'm also using the app "Coin Ticker" for iOS (iPhone), which is doing the same as MyAltCoins. It works really well!

[lucacri]

That's a nice app!

I added the import from LocalDogecoins

Any plans for adding Counterparty (XCP)?

Great site as usual,

[stoner19]

this is awesome! Donations definitely headed your direction. Can you tell us what your plans are to add other exchanges? Poloniex, Mintpal, Bleutrade, McxNOW...

EDIT: also locallitecoins

Thanks!!

[lucacri]

Unfortunately, Mintpal has no private api yet (it's in beta for now), and poloniex doesn't offer an api call to get all your orders, but instead they require you to make a request per each pair of currencies (so, for now, something like 50+ requests to see all your orders).
I'll find out about the other exchanges ;-)

That's the plan

I imagine that someday tax agencies are also going to go after crypto to crypto trades in addition to the current USD involved ones.
I imagine it would be easy to export the USD only trades via a checkbox or the like?

Thanks for the great service, my plan is to make a donation every year.
Best,
IAS

The beauty of the excel file is that you can just filter by currency/date etc. Or am I not understanding the issue fully?

Again, thank you for the donations, they are definitely welcome (and needed)

True, you could "filter" at either end.
I think it is just easier to do it at your end. (But more work for you initially).
Don't mean that sarcastically - I very much appreciate your work.

Little bump for the new users

[surfer43]

Hey, you should merge the old Monero ticker, MRO, to the new one, XMR. Pretty confusing to have 2 Moneros.

Great site!

Nestcoin for sure.
