Oh yeah thanks, I do find it pretty shitty that I "lost" 24$ because of that though, shouldve done more research i guess.

Aaand sry for the late reply, seems like i couldnt post more than twice because of a limit on this site, my bad...

yea it says -0.66 (amount) and balance 0.

I wanted to try gambling on rollbit, and as I made my account on electrum and transferred about 30$ all went well so far.
When I sent the 30$ to rollbit, only about 7$ arrived, my question really just is where the other ~23$ went.

When viewing the blockchain hash, it seems like 0.5 mBTC went off to another address, which I never entered anywhere
I had 0.66 mBTC in total, so after the fee +  the amount that actually arrived at rollbit, it all adds up.

Thanks for any replies...
