Do you spend your Bitcoins or just hodl?
I'm doing both. Holding some Bitcoins while selling some of it

.
If you spend
What for and do you miss something that cannot be bought for Bitcoin yet?
Just for some expenses here in our home. Maybe for some, it might sound weird or the like but at least that is what I'm doing. I would love to use Bitcoin to buy things that I like but there are only few merchants that are accepting it and on the other hand, maybe I don't like or need the things that can be bought using Bitcoin.
If you hodl
For how long and why don't you spend?
Do you have exit strategy or you will spend it after you can buy your desired thing?
I've been holding for 3 years already and I spent nothing to hold Bitcoins since I hold some of my Bitcoins that I got from signature campaign

(best decision at least for me to keep some of it).
I'm not spending some of it because I believe that price of Bitcoin will go up soon and many are thinking the same as me. I have an exit strategy and if I exited, I will use that money to buy something.
