Yeah using doge makes a lot more sense than using btc.
One reason is Doge is designed to grow in price at a slow rate.
Btc is designed to grow in price at a fast rate.
Based on the percentage, many times the price of Dogecoin increased a lot more than the price of Bitcoin. My favourite token/coin for gambling is shiba inu and doge though I usually use USDT on gambling to avoid losing any crypto. If I loss these then I may not be able to re-purchase again but if I loss fiat then I might be able to recover from offline business.
