I am looking for advice regarding the bank to be able to play some tournaments a week or month being a cash player.
Advice regarding the bank destined for tournaments, what buy in ?, have a specific bank for tournaments? I do not intend to dedicate more than one day a week at the most.

Any advice related to playing tournaments being a cash player is welcome, I understand well how to have a good cash bank strategy, but I can't reach a good conclusion when I put the MTT in the middle

Thank you
