So today Mara could test 40, if it doesn't hold, I personally would sell some because, I think, it could retest 28 and be on the side way till next week.
The same situation happened when BIT touched ATH 42K. RIOT and MARA dropped under 20 USD. That was a good time to load more.
It of course all depends on BIT trajectory. it seems BIT will go up but if no steam, it will back down to 40K.
So be carful out there, and may the power be with U!
