I don't know if I understood you very well but it seems that you are replying to a post about staking Bitcoin.
The function is different and dedicated mainly to the other cryptocurrencies and it is not the goal of the plateforme to see people holding Bitcoin there and waiting for it to see their rewards increase.
Any plateforme that is holding major cryptocurrencies including Bitcoin are at risk of being attacked and hacked.
BetFury offers the stake option but after all its main goal is to be a casino.
There's nothing wrong with other gamblers here at betfury holding their bitcoins using the betfury platform using its stake features on their website, right?
I don't see any problem with this.
At least if other users do this, there's still a chance that even if it's placed in stakes and when they see that they have a profit,
they can still use it so they can still play games through the betfury platform, right?
There's really no problem with it especially if their intention is to invest it and the funds they use is which they can afford to let go.
If it happens that what they are thinking to leave it and making this platform as their wallet maybe they might get a problem with it especially they might get tempted to use it for gambling. So deal with funds those they can afford to lose so that they won't encounter any issue if they decide to stake or either want to use their funds to gamble in Betfury. Also more details from here
if they are interested to stake their Bitcoin or other crypto in Betfury.
