please be aware that bech32 addresses (starting with bc) which have started appearing in some wallets are not currently supported by this pool
Why is this? Just not popular enough to add support? The 'standard' has been around for a while now. I've found a few places reject this format, even though electrum has offered the format for some time now.
No code in the pool to support it? I'm also not sure on whether you can generate directly to a bech32 address since it's meant to be segwit to segwit only.
