In my opinion, the one who deserve the appreciation is mostly the founder and also developers of bitcoin, since without them, bitcoin won't be here and of course it'll lack of many things. Other than that, we should give the appreciation to the miners, because their job keep bitcoin alive. Miners have such an important role in bitcoin. Then, i guess we should give appreciation too to us, the bitcoin users that believe bitcoin, willing to buy bitcoin, hyping bitcoin and making it as big as it is now. We, the users, the one who create the supply and demand also need appreciation to keep bitcoin alive and high like now.
