I love seeing bitcoins dramatic growth, consistent increase in price is very unrealistic. I think increasing and dropping number of bitcoin addresses doesn't really matter, because anybody can create and forget addresses. I guess it will not affect bitcoins status.
Definitely true. The chart of bitcoin addresses does not affect whether the bitcoin will fall or continue to rise. Bitcoin will remain alive as long as there are constant demands in it. Addresses maybe increasing from time to time and maybe it will reach to the target limit but not all of them are still active. So why bother to be affected on that chart?
