... I can see this hitting 6500-7000 before reversing back to 9-10k, at this point I'm not sure if selling and re-buying on the following dip is best or if this will rally well past 10k. ...
better hodl or buy some more if you still have money to buy in selling is not recommended at this level, specially if you bought it at $9000
the lowest it will go this time probably around ~$6800-$6900
if it drops below that, most likely it will go down even more to ~$5600 or so
