I was running a decently profitable scalping operation but the time invested made it silly to continue. However, I could really use the $200 in monthly income, and I'm not too afraid to lose the $2000 principal investment if the bot is coded well.
The other option is a video poker bot, which is already freely available. The issue of course is getting it past the casino :)
Actually placing trade orders and closing orders is only a few minutes of work and a lot of waiting/thinking, like chess!
That is to say, 213% gains from trading $2000 on JNUG/JDST is a lot more feasible than 213% gains on $75,000,000 USD worth of AMZN calls
I can buy JDST at 9am for $60 and sell at 9:45am for $60.60. On a balance of $2000, this is an easy $20 for basically no risk, imo.
Sustainable should mean that 500 readers of HN each individually managing their little $2000 nest egg ($1 million aggregate) making independent decisions should be able to collectively be sitting on $3.13 million after a year.
You don't get sustainable 213% returns without a commensurate, sustainable level of risk to go with it. But if you're able to do it sustainably with 3x ETFs, congratulations.
It actually saves money because you're not buying things that you happen to see, and only getting what you need.
