Show HN: GameOfCoins.de – Virtual Cryptocurrency Trading
- eralpb 9y agoHello, 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.
- egeozcan 9y agoGreat 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.
- eralpb 9y agoThank 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 ;)
- Tepix 9y agoGetting 500 server error when trying to buy a cryptocoin.
- drakmail 9y agoSqlite in production? Seriously? And Python 2.7... Move to 3.x and PostgreSQL at least ;-) PS. Nice idea
- eralpb 9y agoI 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!)
- stefantheard 9y agoHow much do you pay for your t2.micro?
- silly_giraffe 9y agoSQLite can handle a lot more than people think. The SQLite website uses it for production (https://www.sqlite.org/whentouse.html https://www.sqlite.org/whentouse.html)
- StavrosK 9y agoIt can handle a lot of reads, but you'll have problems with multiple concurrent writes (at least with Python). I run read-heavy production websites on SQLite just fine, though.
- fazkan 9y agohow did you come to know which stack, the app is using..
- bastijn 9y agoNot 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!)
- eralpb 9y agoHaha 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.
- bastijn 9y agoYou 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/ https://gameofcoins.de/ works but https://www.gameofcoins.de/ https://www.gameofcoins.de/ linked from your page results in a dns error. I guess your dns records need some tuning.
- brut 9y agoI'm jealous. I've been working on almost the exact same thing for a week now. Really jealous. And a bit angry! Haha.
- eralpb 9y agoMaybe 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!
- brut 9y agoNo, 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.
- justinjlynn 9y agowell, if you find yourself not wanting to work on it because someone else did it already, would you consider putting your schema online?
- brut 9y agoNo I'm still working on it. I will definitely consider pushing code to GitHub.
- ringaroundthetx 9y agoCan't go short? nobody can make returns on a down day except possibly selling back to USD?
- eralpb 9y agoI 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 :)
- ringaroundthetx 9y agoshort sells have nothing to do with stop losses and complex order types. but, alright, permabull virtual virtual currency trading.
- matt_wulfeck 9y agoYou've virtually described the current state of bitcoin. People buy it and never sell it and never use it.
- ringaroundthetx 9y agoand thats okay. the M1 money supply is a tiny fraction of the currencies people actually respect, so it looks like bitcoin is working at the same standard those are held at.
- noddy1 9y agoNext 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
- jerguismi 9y agoWhy not just go straight to the ICO? Most projects seem to do that and they still manage to raise those millions.
- quickthrower2 9y agoBiasCoin
- luismmolina 9y agoWhere is IOTA? I want to "buy" it. Keep working on it, its really nice!
- eralpb 9y agoIt is interesting that IOTA is missing.. because I already query 1300 coins. Let me check what is wrong :)
- hayksaakian 9y agowould be nice to track my trade history so i can see when i'm up or down on an particular coin
- eralpb 9y agoIt should now be implemented ;) .. half of it lol
- Retr0spectrum 9y agoSomeone seems to have hacked it already: https://gameofcoins.de/portfolio/bury https://gameofcoins.de/portfolio/bury Race condition?
- Geee 9y agoYou can make much more profit trading here than is actually possible, because buying virtually won't affect the market.
- Tepix 9y agoYes 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.
- Keeeeeeeks 9y agoNeat 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
- techaddict009 9y agoWow we are competitors: https://www.cryptoground.com/ https://www.cryptoground.com/
- eralpb 9y agoYours looks really nice, keep it up ;)
- Sujan 9y agoWhy the .de domain? Feature request: Let me input exact amounts instead of only via the slider.
- kentbrew 9y agoBought some DOGE, sold it back, and now have $0, at the very bottom of the leaderboard: https://gameofcoins.de/leaderboard/710 https://gameofcoins.de/leaderboard/710 I have company, though. :)
- rrobukef 9y agoYesterday I subscribed. Today I get spam. Anyone else?
- eralpb 9y agoI don't even ask for email.. how can I spam? :/ There is no "subscription" on the website.
- ddgflorida 9y agoFun! It would be nice to see what price we bought the currency at in Trade History, plus what our current profit is per currency.
