So what if you are 20 or 21? After a month will you feel like an infant?
I wrap my money similar to MaxPen, but I suspect even smaller packs of $1000, using either a rubber band or sometimes a large paperclip. The reason is being a table player, I don't want to pull out a brick of 10 or 20k and start peeling off hundreds at the table. I don't want other players and just people milling around to see that and I also don't want the pit to know I am well financed. That just screams AP when playing blackjack. By buying in for $1000 or sometimes two of my thousand dollar packs when playing games with higher maxbets, it just gives the appearance of a player "chasing" losses. Even if you do so several times in seccession.
