Casinos have vaults you can put some of your wins in and leave them there. You can also put some of your winnings into a cold wallet. What keeps you from taking a persons coins that they sent to you and disappearing?
Just doesn't really make sense to send coins to you honestly. I'll admit I haven't clicked on anything and read anything more than what you have posted here, but from the go it just looks like a possible way for users to get scammed.
A casino vault keeps you one click from redepositing. Cold storage is great, if you already have the discipline/workflow (which many players don't). Piggy is the easy button for that habit (separate place + lock + reminder).
And yeah, we know some folks won’t click but will still reply, signature-campaign counters gotta spin 😄. No worries, that’s the gist right here.
