Re: What about those bitcoins that are LOST?

Lost Bitcoins is a good thing actually. They make your unlost bitcoins more valuable. (As long as the lost ones aren't yours of course)

I don't think so: nobody knows anybody has lost his coins, there's no way to know it, apart the case I exposed in the previous post, or by admission of the user himself, which can be fraudulent.
AT THE MOMENT the value of your coins is UNAFFECTED by lost coins.
In the future, when we'll hit the wall, THEN this may affect it, as less and less coins will be in circulation.

i presume that the impact would be very low on the market, do not expect an huge rise in demand only because 30% of coins are lost, people simply will buy less one whole btc and more satoshi or bits

Not like that.
In a possible future that we all are hoping, Bitcoins will be a used everywhere by everyone.
There will actually be scarcity of them.
People won't BUY bitcoins: they will USE them and EARN them with their work (until AI and robotics will take all of that...).

Yeah but it will take time for the scarcity as the majority of the population is not aware about the bitcoins but in future when bitcoin gets into the mainstream people would not be able to buy them but those who will be holding great number of bitcoins can earn a good profit by selling it.
