No, I never tried to mine btc actually. And will never do.
I used that kind of websites:
http://dailybitcoins.org/I understand exactly how bitcoins works, how mining works ...
What I don't understand is why the price is so high (~ 90 euros). It does not make sense to me.
So, make it simple: what makes that high price? High supply.
Where did it come from? And why?Quite simple, if you had read my entire other reply. The price is so high due to speculation. People thinking they can make a quick buck (or euro) off of it. Bitcoin certainly deserves a higher exchange rate than the 1 euro to 1 btc conversion you suggested earlier. After all, we know that there will never be more than 21 million BTC however the ECB and the federal reserve both create (and dump into their respective economies) more than 21 million units of their respective currencies in a single day on average.
So your idea of a 1 euro to 1 btc equivalency would mean that BTC was constantly losing purchasing power. Why tie it down that way, just to make things more convenient for you? While we're at it, if we're going to do that, why don't you make a grand statement that 1 oz of silver is worth 1 euro and 1 oz gold worth 10 euros. See how much you can purchase at those prices.
The price BTC
should be at would be discovered by 'price discovery' which is what people are willing to set the value at. This soars when people try to abuse the system to make quick buck.
The price BTC
is at is due to speculation, from people who don't care about the cryptocurrency itself and (much like it sounds you feel) just want to be able to make some money off of it.
Now do you understand why the price is so high? Because that is where the speculators have driven it. There is no high supply of BTC, so I don't understand that part of your question. If you don't understand now, kindly go read up on economic theory and then re-read the answers in this thread and perhaps you'll understand then.
