The miners mine and hold, other mine and sell.
Investors and speculators buy, hold and sell.
You can buy random items in auctions and through the forums.
What are the reasons for the bulk of the bitcoin transfers? I read an article underlying the "dark side" of the internet and TOR network, and they seem to point out that bitcoins are now nearly the exclusive currency for the online "black market" (Note, they are not saying bitcoins are exclusively used for black market transactions)

I am in a category of investor because I bought Bitcoin last March 2017 then hold it but just a small ammount maybe $25. I just did it and give it a try but it really work for me.
All of my funds received from campaigns will be transfered to my main wallet for me to save it there. I will only convert it into fiat in time of emergency. I choose to hold Bitcoins for future purposes. It is really hard to buy now since the price is very high. My only concern is the high fees also but happen to be no choice.
