I think btc crashing and prices going down are different things sometimes. Of course, if btc crashes the prices will inevitably go down. However, they can also go down in other cases like robberies of some big markets or people getting nervous that btc may crash and selling everything because of it. Now bitcoin is nearly $2800 which is totally fine. We can't prevent panic selling in general but we can keep calm ourselves and contribute something into anti-selling this way. As for the crash, the miners have to support the implementation as much as possible and this will help btc to stay the king.
Its basically the same the only difference between them is price crash in economics means a sudden significant drop on price. on the other hand price down/fall means exactly as
it sounds regardless the situation as long as there is a decrease it is considered a fall but if its not sudden and significant obviously it won't be considered as a crash.
what do you mean anti-selling? selling is a signifcant part of the market if you removed the selling part, the system will fall. Crashes is inevitable and its not always a bad thing
sometimes its an opportunity.
