Ah, no, you did not... "If you produce less bitcoins (in the life of the miner) then the miner cost (in bitcoins), then mining activities has created a loss " <-- Most of the time when people start using this argument, they also say that it would be better to spend that money on BTC and save it than purchacing the mining equipment as you'd have more money in the long run. That is why I used the horse and water analogy... if a person can buy and wait they should and would be ahead, but not everyone can.
People mining for profit should do their best to separate profits/losses from mining activities and profits/losses from speculation.
If anyone is trying to determine if they should start a mining operation (for profit) or speculate on the price of bitcoins(for profit), they should do their own research and come up with their own conclusions. Random people on some forum may not be giving the best advice.
