1. Whenever you say "ROTFL" - you really show your age (presumably in your late 50s, even 60s perhaps) - nobody says that anymore.
2. "Meanwhile nickel (and most other minerals) is suffering from lower grades, higher production costs and lower profit margins.". Given you're retired, please dig up some evidence on the three points you've made above. 1) lower grades, 2) higher production costs 3) lower profit margins. Now don't forget to adjust for inflation.
3. You still haven't answered the core point I made - why is it a bad thing that the price of nickel (as you claim) is the same adjusted for inflation as it was in 1994. For example, plenty of people, significantly smarter than a person who goes by the name of 'PigsMightFly' on an internet forum purchase and invest in gold, which according to your side-kick who replied to me earlier, is the same (adjusted for inflation) as it was in 1980s. Again, before spouting bullshit please complete your assignment outlined in point 2 with reference to my query in point 3.

Don't forget the graph I mentioned earlier.
