a bubble is never good for the long term health of the bitcoin market, it creates panic sell/buy which will keep most investors and normal people from trusting the coin.
You should not care for the long term health of any market. You should not care for investors and normal people. You should only care for yourself and for here and now and how much profit you can make out of a bubble if it appears.
There isn't a bubble yet.
Some of us were not raised by sociopaths...
It is neither about how to be a human nor how someone was or was not raised. It's about trading. Either you win or you lose. Is losing humane and winning sociopathic? I don't think so.
In a sociopathic mind that is correct.
However, some people have minds that work differently and look at longer term and communiy wide effects. For example, it might be that someone is coding a more efficient miner to produce bitcoins and secure the network, this is a market activity that results in long term returns which a sociopath who sees the world as a seriesof zero sum games might not be able to understand.
The reason why this market exists is because a lot of people want to break free of dependancy on fiat. Sociopaths do not care about that unless it profits them.
