BTC has crossed the mark of $43k after a while and will it pump further towards $50k
We're all guessing and no one will give you if it's a yes or no accurately.
and is this the buy in period or else it will once again dump and stay around $40k for some more time?
Just expect that every time bitcoin recovers, a dump again is waiting. It's an unending cycle that we have to consider all of the time. It may pump a little this time but who knows, by the next days, it will be bloody weekend again and will dump more than its recovery.
IMO there are more possibilities of bitcoin recovering from recent correction and March towards $50k which will send green signal for entire crypto market and we have even noticed it's positive effect today on top altcoins, what's your take on this?
No matter what the move of bitcoin is, for sure alts will come with it but some of the alts will also have their way. Pump or dump, whichever it is, just have your own bitcoins collected and add more if you can.
