Both holders and watchers rejoiced because they believed that this time, the end of the long-term resistance may signal the beginning of a new rise.
I don't think too many people expected what you say here, or you are just making the claim without any thought put into it; people who have the understanding know how the cycle works, they know and have learnt from history because it tends to repeat itself, if there were people who had rejoiced that a bull run was beginning, they have to learn more through BTC history now.
Whatever news site this is, i feel they are trying to build up fud, the news headline makes it look there is some kind of risk in BTC's security when there is none, hash rate is very high and even the person who wrote that article knows that there is no threat to BTC's security and that it is all fine.
