Obviously there is opportunity to make alot of coins this year with cards going up and down on a daily basis. I know the whole buy low and sell high mantra so please dont give me that. But genuinely speaking, what are your tactics: is there a certain day cards are cheap/expensive; are some positions better to focus on; are there distinguishing traits that indicate a card will drop/rise?
I have had some success but its been difficult lately given the market crash
