And there are a few people who hold a huge chunk of the Bitcoins. Does that make it a scam too? So a few people with big hash power were quick to mine a chunk of them. So what? More power to them.
No, you don't get it yet.
The principal fact is, that the minging algorithm was designed for to mine WHOLE HALF of the coins in half an hour.
It is unfair - early privileged miner or miners (the only informed), were getting coins with uncomparable easyness in comparison to hard working miners later.
This is scam.
Look at bitcoin halving algorithm - it is completely different and it is unbiased. Everybody gets coins proportional to his work.
Halving periods are much longer, and are designed to counteract increasing hashing power, for nothing else, to retain fairness even more.
And regarding "huge chunks". Do you think that just few people do own HALF of the all bitcoins, that will ever be mined?
