how much to keep online

[CAMEL1111]

Like others have said, only keep money online that you are prepared to lose.

Leave as much as you need and less than will keep you up at night if you lose it all.

if its a small amount of money I wouldn't worry about it...
if its a large amount of money you could have it invested somewhere else and only keep what you need online

Whatever goes above my 25 buyins for the week i'll cash out.

I think american players have a much harder time, because it is much more difficult to reload so I suggest keep more at least 50% more than your standard acceptable bankroll for the stakes/games you play.

Being in Canada myself I don't have as much trouble, but loading with bankwires is expensive so I actually keep about 7-8K online I play around at NL100-200 mainly.

I used to keep more, but moving the money into GICs or high interest savings accounts, the money actually grows which is good.
