This statement is not comprehensive. I think BTC is neutral, not good or bad.
If BTC brings benefits, users will think it is good; On the contrary, if it threatens the interests of users, BTC is bad.
People are egoists, which may be good for you and bad for others. We can't think that bitcoin is unfriendly.
Wise words to say, the usability of bitcoin depends on the prices, if it is in red, people that only have a small brain capacity will say that it is useless and if it is in green, the very same crowd is going to be saying that bitcoin is really useful.
