The only coins I see in green mode is ADA. I do not know what. Maybe the technology behind or upcoming events have some decent effects on this coin
But, exception for pump and dump shitcoins those coins definitely could have any pump or dump moment like literally at any time regardless the condition of the market if the whale behind those coin decide to pump the it's gonna pump
but that's only temporarily, honestly though at the bearish market people should NOT use pairing for crypto against USD, it's better to use pairing against BTC, basically to help you focus on increasing the number of btc owned.
