Dropshipping is like MLM, but the scam part happens after the purchase. Often times the dropship supplier doesn't accept returns, meaning that when the customer returns your product which you have no real quality control over, they get their money back but you don't. The idea that these sorts of online arbitrage opportunities exist or have any durability when everybody has access to Google is flawed.
In reference to the comment two levels above this one, there is no better representation of HN than somebody who has no idea what they're talking about sounding absolutely convinced about themselves and then not only being wrong, but almost diametrically so.
Most people can read "unsavoury variety in the cryptocurrency sector" as everything except bitcoin. A minority of people will read it as "all crypto", and if you're reading it as "only shitcoins" you're probably a little unsavoury yourself.
I was at a hackathon and this big shot legal person from NY was telling me about a hot crypto company and them using Haskell was like the first thing he told me. In fact, all he told me was they raised a bunch of money in an ICO and they use Haskell. And then he sat there waiting for me to be impressed
Haskell always struck me as a language you'd want to use to feel superior to the people who code in JS and python, and crypto always struck me as a field you'd want to work in to feel superior to the people who work in industries that actually generate profits.
Also, another possible reason is that many crypto people tend to confuse complexity with ingenuity. While the bitcoin whitepaper tries to make a complex topic as simple as possible, a great many crypto companies and people purposely use language that is needlessly convoluted and verbose.
Perhaps they're doing it on purpose to seem smarter?
