Next step is to rank the participants, start making actual trades based on the top 50%, then ICO a coin promising a share of those profits for $30 million in ETH

jerguismi8y ago

Why not just go straight to the ICO? Most projects seem to do that and they still manage to raise those millions.

Hello, I created this for fun, although more professional tools are available for virtual trading this one is just focused on cryptocurrencies and for the fun aspect. The cryptocompare's API is used. I am willing to develop this a bit further, currently it's just a day old project.

egeozcan8y ago

Great idea, now I can see how I would suck about making the right coin choices! How about also showing the buying price to make it more apparent for me? :)

Also, something to keep in mind: There are occasional errors about database being locked.

eralpbOP8y ago

Thank you, I may implement couple of features this weekend, I agree it'd be much better to see a bit of history!

Changed my database server, should give no errors as of now ;)

Getting 500 server error when trying to buy a cryptocoin.

You can make much more profit trading here than is actually possible, because buying virtually won't affect the market.

Tepix8y ago

Yes it should take into account the trade volume and if you buy a significant amount there should be a penalty fee to emulate this somewhat.

I'm jealous. I've been working on almost the exact same thing for a week now.

Really jealous.

And a bit angry! Haha.

eralpbOP8y ago

Maybe you tried to include too many features? :) My friends just wanted to give cryptocurrencies a try, and all these charts and orders are too complicated! This is where they can create a portfolio in couple of clicks and check it weeks later if they feel like it!

brut8y ago

No, my idea is slightly more involved. However I want to use my own data, not other people's, so I spent time setting up a proper DB schema to hold exchange data from various providers. This is not complicated but also not trivial.

Wow we are competitors: https://www.cryptoground.com/

eralpbOP8y ago

Yours looks really nice, keep it up ;)

kentbrew8y ago

Bought some DOGE, sold it back, and now have $0, at the very bottom of the leaderboard:

I have company, though. :)

Keeeeeeeks8y ago

Neat project; I'm starting to think that most of these sites, and services that gamify crypto-speculating are training models around user behavior/mimicking trades.

Also, it threw a 500 internal server error after linking Twitter

Someone seems to have hacked it already: https://gameofcoins.de/portfolio/bury

Race condition?

ddgflorida8y ago

Fun! It would be nice to see what price we bought the currency at in Trade History, plus what our current profit is per currency.

hayksaakian8y ago

would be nice to track my trade history so i can see when i'm up or down on an particular coin

eralpbOP8y ago

It should now be implemented ;) .. half of it lol

ringaroundthetx8y ago

Can't go short? nobody can make returns on a down day except possibly selling back to USD?

eralpbOP8y ago

I didn't want to convert this to a full-fledged trading platform with Stop Losses and orders etc. it requires too much effort. but if you want to test that I can recommend you Etoro's virtual mode. But thanks for your comment :)

ringaroundthetx8y ago

short sells have nothing to do with stop losses and complex order types. but, alright, permabull virtual virtual currency trading.

Why the .de domain?

Feature request: Let me input exact amounts instead of only via the slider.

luismmolina8y ago

Where is IOTA? I want to "buy" it. Keep working on it, its really nice!

eralpbOP8y ago

It is interesting that IOTA is missing.. because I already query 1300 coins. Let me check what is wrong :)

rrobukef8y ago

Yesterday I subscribed. Today I get spam. Anyone else?

eralpbOP8y ago

I don't even ask for email.. how can I spam? :/ There is no "subscription" on the website.

drakmail8y ago

Sqlite in production? Seriously? And Python 2.7... Move to 3.x and PostgreSQL at least ;-)

PS. Nice idea

eralpbOP8y ago

I didn't know Python3 offers better performance to be honest, but Sqlite is a real ordeal for this t2.micro now ;)

(Switched to PostgreSQL in a hot-change fashion!)

silly_giraffe8y ago

SQLite can handle a lot more than people think. The SQLite website uses it for production (https://www.sqlite.org/whentouse.html)

How much do you pay for your t2.micro?

how did you come to know which stack, the app is using..

binora8y ago

wappalyzer is also good[1].

eralpbOP8y ago

I had the Debug mode on, which gives MANY information about the stack and all that :)

Not sure if this is a nice idea, a nice execution, or nothing at all. There was a HN post not too long ago on "please tell us what you do first thing". Guess you should (re)read that. Any action requires my twitter or a new account. And you call people without Twitter old school?

Jokes on you!

(So:

1. create a proper landing page

2. Allow us to check on what this is without sharing our data with you; because we won't without knowing what this is in this era.

3. Twitter new school? Ha!)

eralpbOP8y ago

Haha sorry to offend you, I meant to say like Username/Password is kind of old-school in this era where the importance of digital identities are realised and there are many startups around it, Twitter uses an Authorization protocol (OAuth) which makes them "new school". I quite dislike Twitter.

bastijn8y ago

You didn't offend, no worries. I understood what you meant. I just included it as a minor, not well understood it seems from the downvotes, joke to take the edge of the comment. My main message was you should update your landing page to explain what it is. That should reduce the bounce rates. Having to sign up without information on what you are signing up for is a big barrier and might (will) scare people away.

P.s. https://gameofcoins.de/ works but https://www.gameofcoins.de/ linked from your page results in a dns error. I guess your dns records need some tuning.
