it's just a term when the market is falling and the market is rising as a whole. so if you see bitcoin and all altcoins experiencing a drastic increase, then it's a bull run and if the opposite happens then it's a bear market. but if the increase or decrease is only 1 coin or token, then it will not have a big effect on the crypto market at large.
When only 1 token gets pumped or dumped and you can call it as a pump and dump token. This kind of token was actually created by scammers and only gamblers who have been buying that scam token. The global economic is a thing that triggering everything to decrease.
The inflation has been making everything become very expensive but it's not straight with salary that received by anyone who has been working in real life. If global economic is still collapse and crypto will never increase.
