There is a third-party risk when you keep your bitcoins on a website, a lot of us want to avoid this risk but it's interesting to consider the options to invest a portion of your bitcoins holdings and get a positive return instead of having your bitcoins just sit in the wallet.
Just-dice was trusted and successfully returned gains to investors : you could invest in the site bankroll and play against the players with a 1% edge.
As I know just-dice accept only Clam, not BTC, and and are unstable enough( In October price dropped from 0.0023
BTC to 0.0005
BTC 80%!!!
the principle is the same, but just-dice additional staking clam and pay around 2.5-3% reward per month.
