People that store bitcoin for fun are those who are stinkingly wealthy....... Theydont care if the value increases/decreases...
I store it for future purpose and not for fun...
You're quite right actually, I've noticed that as well. People that have been mining Bitcoin since 2010 or so have mined the coins just for testing purposes and put them somewhere for years. I am pretty sure that the people that lost their Bitcoins because they forgot where they put their wallet wasn't thinking that the price was going to get passed $1,000 per coin.
If the people want Bitcoin in the near future then I would suggest that they hold onto their wallets and not worry about it.
For me only holding them is a very boring process so I will give a try to grow them by doing trades and investments and if luck favors me then I will be growing my bitcoins in really quick time and at the same time it will give me instant profits too as holding will never grow amount of my coins.
