Nah I'm just stating facts and nothing more. If I want to use bitcoin to bet, I need to buy some bitcoin from an exchange, and then pay around $20 worth in withdrawal fees just to deposit to a betting site. Sure if u already have some bitcoin handy it's not terrible but transacting bitcoin using exchange is horrible and it's a fact.
If exchange charges you their own fees on top of miners' fees, then they probably do the same for ETH and other cryptos. Anyhow, you can't blame Bitcoin for such fees, just use different exchange ffs. I think BitStamp has free BTC withdrawals.
