Thats true due to the small fees altcoins are usually the best for stuff like this ( minus etherium ) but doge , LTC and polygon , fees are really encouraging, and they are also fast .Like then I was using LTC and BNB to deposit in platforms and it literally save a lot of fees .
Not only that you save a lot of fees and time if you deposit or withdraw altcoins like Doge, trx or Litecoin, but at the same time, you can bet or gamble with very small amount. For example, you can bet or gamble with (example) 10 trx etc and even if you lose, it is only pennies. I think there would be a very small percentage of gamblers who would be using Bitcoin or Ethereum for gambling purposes. Even stable coins like USDC or USDT are also very popular, but I prefer TRX or DOGE (my favorite coins for gambling

)
Doge is not designed to grow in price by a lot.
This is due to its inflation rate. which lowers every year but is endless.
year 1. x doge coins
year 2 2x doge coins to a 100% inflation rate.
year 3 3x doge coins or a 50% inflation rate.
year 4 4x doge coins of a 33% inflation rate

x
year 10 we have 10x coins
year 11 we have 11x coins this is a 10% inflation. rate we are in year 11 so the current inflation rate is 10% which is close to the same inflation rate on cash which is why the price grows slowly.
So If you play all year long and lose 100 bucks in doge it is not mooning like btc will
now in year 20 or 2033 to year 2034 doge will do 20x to 21x or a 5x rate of inflation
which is a little better than cash.
So it is kind of safe to play with doge as it won't moon that much
but 2030 to 2039 I expect it to go up better than now.
Remember I splaying the mathematical inflation design and my description is good ,but people do not always follow good and correct info.
