Yes it is.
People always forget their passwords, send their money to the wrong address, get their computer broken etc etc...
The available number of bitcoins are decreasing every day.
I dont agree.... saying that bitcoins are decreasing is the same as saying number of lost bitcoins is higher then generated bitcoins. and its probably not.
Wait, wait. I dont think we are on the same page here.
Available bitcoins are the one's being mined now right? Right this moment. Yes it is decreasing. I have read that there is a limit to the maximum mined bitcoin so if there is a limit? then it will be depleted right?
