I find having an all cash bank to be the easiest to manage. I usually keep extra cash on hand, or players will Venmo each other if they need to rebuy. Essentially, money goes into the bank before chips are dispersed.
I run a .25/.50 game with $40-$50buy ins, as host I usually have three buy ins for myself, and about an extra $100 if someone else plans on Venmo during the game.
