I wouldn't say that HFT arbs out only the "obvious" things. We try to arb the non obvious things as well, with more or less success. HFT just means you trade a lot and you have low tick to trade latency. It doesn't say m

The order book provides liquidity. When someone sells a swap, someone else buys it. Of course, the amount of liquidity and spread available will depend on how popular the coin or specific contract is.

Well that mechanism for arbtrage usually occurs through settlement. ie at contract settlement, you trade one for the other.

There's a good reason for that: life is cheap among poor people and poor countries because they have little to lose and a lot to gain. The payoff is asymmetric for violence, so it's a rational trade.

We rely on cash payments for other things to, like info about criminals and such. Why should we expect people to do hard things unless they are in their best interest? Regardless of morality, that's just how people are. This isn't

Saying no retail investor should be buying stocks is like saying no one should ever start a company.

I'm lazy and dumb it's true, but I like ordering off of Amazon for most things. I just don't really care about the 99% of things I am forced to buy in order to live a somewhat comfortable existence. The most important thing I

I like beets, but sometimes you need to clean up the tags. A long time ago I made a curses based tagger where you can clean up tags. I still use it today and imo, It's the best tag editor on the market! https://github.com&#x

I feel like most people don't use WhatsApp in the US? Or at least, I don't (regularly).

There's of course a ton of luck involved but you won't get struck by lightning by sitting at home. I've tried to increase my "luck" by forcing myself to do things that have an asymmetric payoff: meeting new people,

Sure, but is betfair a scam too? Or what about an OTC desk? Both of these are similar to bucket shops wrt who's the CP.

by smabie 5y ago
Bucket shops have historically offered high leverage, something that is not possible when buying equities outright. There's a whole gamut of different kinds of bucket shops, some being on the less shady side others on the outright take

I mean, honestly haven't met that many people who've had a problem with cocaine either. Opiates on the other hand, that's a different story.

Ketamine has much lower potential for addiction than, say, alcohol or opiates.
