coins with very short block times demonstrate the ability to take almost 100% of the rewards with enough hashrate to orphan everyone else trying to mine
This is almost certainly intended behavior by their creators. It allows them to premine while maintaining the illusion of "fairness".
Yes, even with smaller block rewards for early mining.
It is literally a race of seconds for the first person to throw several dozen Megahash at the network.
once you have it, you control it. Everyone else will be orphaned.
I'm not sure.
I was buying lots of Worldcoin from several different users maybe an hour or so after launch.
But I see what you are saying in theory.
sockpuppets are common, anyone who isn't an idiot at this will use them
nobody is going to touch a coin that someone premined a massive % of coins. There's literally 5,6 maybe even SEVEN figures of profit on the line, the people premining need to keep the illusion that it's a coin "of the people" before they dump.
