Yes and as for now on such low difficulty
less and less total BONES coins exist
means it become more rare and valuable as for now
on difficulty 0.1-1 only about 1.1 - 1.2 millions BONES
exists.
Stop saying that. It's simply not true. Difficulty going from 10 to 1 basically halves the total amount of coins, but it makes it 10 times easier to mine. This makes it 5 times less valuable to mine in the short term. So stop saying it makes it more valuable. Lower difficulty = less valuable in short term.
