1) A lot of very small amounts from trying out various coins, and mining on multipools. I trade most coins instantly for BTC though.
2) In march 2012 I mined BTC/LTC for a few weeks, but was very busy with university so lost interest. Started again in december 2013.
3) Yes
4) I don't have enough time to actively do research, and invest/mine very new pump'n'dump coins. I benefit in small ways from them by mining in multipools that adopt these coins fairly early.
5) As I am interested in the internal workings of crypto-currencies in general, I like the quality-coins (B) more as they may have an impact on the future. I even spent some time thinking about how to improve them myself. I see mining more as a hobby instead of a way to make money. Being honest however, for mining I just pick the most profitable coin. Sadly, those are pump'n'dump coins (A) most of the time. I think this choice is based on me thinking that my puny hashrate won't make a difference.
6) Yes, definitely
7) For the motivations mentioned, I would even pay a higher price. After all, that's what life's about, no?

I think alt coins have a positive influence on crypto-currency. A lot are copy/paste, but they raise questions and sometimes deal with problems. Eventually this will lead to improvements.
9) Yes, I think people that put a lot of effort in their job or elsewhere will eventually get noticed, and rewarded for it. Karma is a good way to motive yourself

10) Very sceptical about it. If what you say is honest and can be performed, it's a very nice dream/thought/idea. I think you have to provide some more info and certainty however to attract people in a forum filled with scammers.
