If I make profit then I’ll make sure to get everything even if I gamble occasionally since I want to enjoy that profit and spend somewhere else. I guess as a small time gambler leaving some funds on the site might still be ok especially if the site is good enough to ensure your security and you can really trust the site. Though it’s too risky if we are talking about huge funds here because if I have that money it’s ok for me to pay for the fees as long as I have my money in my wallet and have the control over it.
i am fine with leaving some funds also from time to time. if you feel you need to bet some lines later on. but if not, not really leaving funds even if the casino is a very reputable one. sometimes unexpected circumstances may arise like you can't access your account for so many reasons, like you lost your phone and you can't use your 2FA, or unforeseen attack to the site. you'll never know what will happen, so better secure your funds and just transfer when you need to play.
