Recently since Bitcoin are up trends but all most all alt coin are bleeding badly. Really it wasn't expected

. On previous record we can see if Bitcoin bump tham alt was bump more. I don't know the exact reason for that. I guess alt are waiting for Bitcoin ETF ( Excahnge Traded Fund) for SEC approval. We expect midle of next month we can see the result. Till that alt coin holder should be pataine. At least Bitcoin on bulls run that is good sign for alt holder. Once a time alt will bump too.
When bitcoin goes up, altcoin goes down for few days and then they go up. It's not a new thing and most likely expected outcome after a long bull run. Exact reason is money moving from altcoins to bitcoin in some stance but that's no the only reason. It'll change though.
