I have been running AutoLytx my side-project for 3 years strong now.

Stock trading robots: I have been running them for a long time with great success turning my full time job into a side project of sorts... It is based on fear and greed, so I project to run for a long time still... maybe until the real AI take over the stock market... or maybe the AI will also be afraid and greedy like its human parents... so it might run some more :-)

  Could you please give a high level overview on how one can get started with this? Im new to trading and learning valuation etc. I wouldnt mind writing my own bot and playing with various scenarios! Thanks!!

    OK, high level: you came up with a sound idea about trading strategy and go and backtest it for AT LEAST one market cycle, the more you test the better/robust your system is going to be... After you find a working one, you set your risk level, e.g. what percentage from your capital to risk per trade, the best to start is to use Kelly criterion (usually half Kelly for the stock market) and you go from there...

    It is going to work, the problem is that the whole environment is too risky for me... I would not put let's say 200k or 500k into an unregulated crypto exchange, with no government insurance and protection for my assets... Not to mention they are a huge target for hackers, and the lack of government regulation can hurt a speculator like me, there is nothing to prevent the exchange to do a lot of stuff which are illegal in the regulated stock market(and you can actually go to jail for...)

I created MyPost in 2015... never advertised it, save for a few mentions on Twitter and Hacker News. Lets you create a web page in seconds. 4,000+ posts created and being used worldwide.. I've seen as far as Russia, South Africa, Philippines. Free to use. So I feel that it has definitely stood the test of time if people are still using it. https://mypost.io https://mypost.io

  Something similar happened to me with https://markdownshare.com/ https://markdownshare.com/ - I didn't really promote it, but I see it being used from all over the world.

    Your HTML is being served as plain text for me. Tried with both Chrome and Safari on my Mac. Funny enough Chrome just displays the HTML in the browser, while Safari downloads the HTML file. Sounds like a cool service though.

      Weird, checking with curl I see the content-type is set correctly, and seems to work with chrome/firefox/lynx on my linux system. I'll try to dig deeper in the near future, but without a mac I might be out of luck :/

  If I were to start such service today how should I do it? Is SEO the only way? Now if I google "temporary email", top results rarely changes

    I a saturated market, you'll need marketing. SEO should be part of that.
