On the contrary, I think a massive saving and storing of bitcoin can be positive to impulse the price higher because of the lack of supply and an increasing demand.
True but there is also a bad side on just piling up everything. We know bitcoin is not really that popular yet. Yes it will increase in price but with just a number of users. We need more that will adopt and that can be seen if people keep using it and saying "Hey this bitcoin got a lot of features."
It is better for people to use the bitcoin, but it is not so easy now. It takes long time to get confirmation.
