Don't keep a huge amount of money in poker sites/Neteller, if pheasible. Say you have a $5k BR and play NL100, there's no sense in keeping anything more than $1000 on a site (even less if you play less tables) or more than $1000 in Neteller (for juicy bonuses etc), you can then keep $3k of your money in a safe place! Or possibly $1k on another site and $2k in a safe place - still better than having it ALL floating around online..

Personally, when I cash out money from a site, I cash it out to my account from Neteller as soon as it gets there. I keep enough in Neteller to make a deposit into a room, nothing more. When I get over a certain amount in a site, I cash out the excess weekly.
