> But the fact that early adopters are psychotically rich for doing nothing is... one of the many signs of a flawed system. No they risked their money with a speculation that had almost 0% chance of getting any return in the future. They took a huge risk, without this, bitcoin would not exist. And that's why they are rewarded: Taking a risk that almost no one would have taken to create something big. > Basically if e…
Isn't bitcoin easily manipulated? Let's say I have 1% of all bitcoins. I sell half of them, wait for the price to fall, and buy back to have 1.1% of all bitcoins. Repeat each few weeks, and let's say there's 20 people that realized this and have enough bitcoins for this to be feasible. End result = currency that's mostly owned by a few people. And when everybody realize this - bubble collapses. At least that was my t…
But I guess it wouldn't work because if you sell a lot of bitcoins you couldn't sell all at the same price.
Eg. you want to sell 10k Bitcoins. The price is 750$ and the first 50 Bitcoins you can sell for 750$. Now after that there are not enough limit orders anymore available for that price category. So you would sell a lot of bitcoins for much less than the price was originally when you started selling.
And vice versa if you buy them. So I would doubt that you make a profit (because you can't sell/buy at price x and then afterwards the market price reacts. The market price reacts already while buying/selling in large quantities).
As I see it it's the same principle as if you own a large part of a stock, there you could argue the same.
