Only if you're switching computers the whole time. Your withdrawal amount and address is saved in your app data folder along with some other system settings and your most recently used settings file. (C:\Users\yourusername\AppData\Roaming\DiceBot2\)
You will find 3 files in that folder: setttings -> your most recent settings
Psettings -> system settings, like email, sound notification, donation mode settings etc.
settings3 -> Your withdrawal settings and quick switch folder etc.
If you are switching between computers, you can carry that folder along with you to easily carry over your settings. If you're only using one computer, it should be remembered by itself.
I DO NOT recommend that ANY ONE EVER replace files in that folder with files received from someone else, or send them to anyone else. If someone wants your settings (I'll often ask for settings to reproduce an error, or if you want to share it), use the export function and send ONLY that file. If you received settings from someone else, only use the import function under file->import.
