I'm having trouble finding a casino will allow withdraw amount of 0.001 or less
Every site I've tried so far doesn't let you - Am I looking in the wrong places, or they simple don't exist?
I'm afraid for now there's a specific reason making that impossible. Good exchanges and casinos let you withdraw anything above the transaction fee. 0.001 is currently $15.24, whereas a regular transaction fee varies from $20 to $30. That's why you'd better choose another currency for gambling until people calm down and stop operating with btc so much. For gambling purposes dogecoin is very good. It is accepted highly among different websites and the coin is cheap itself, so the transactions are so cheap you won't even notice them. Crypto-games (
https://www.crypto-games.net/) is among the most popular casinos. They have roulette and they accept doge with a min deposit sum of 100 Dogecoin, but even they have a min 0.002 withdrawal in btc or altcoin in equivalent money.
Of course, no one is using bitcoin for transfers if it can be avoided, ideally the casino will support litecoin, dashcoin, etc, or whatever so transfers can be done for less than 20 cents as opposed to 20 USD.
I should revise my question - Are there any casinos that let you withdraw the Equivalent of 0.001 btc ?
