Yes I was very surprised that bitcoin for half an hour added almost $ 600, and I think it's a sign, the wound is coming to life and now there will be big infusions of money in bitcoin and it will continue its rapid growth
rapid growth = crash. remember what happens on january do you want that to happen again i prefer bitcoin will grow slowly it would hurt us alot more if that crash happens again.
And involving the cost for bitcoin or in my understanding I really think if you are referring to the fees of bitcoin right now it is sure are increasing.
the transaction fees would decrease alot if people use segwit even better if they use lightning network.
