I lost not one but TWO entire volumes to it in the past few years. Just one day they wouldn't boot. I wasn't using encryption and I wasn't using any RAID feature, just compression. The people who think BTRFS is a viable substitute for ZFS have just gotten lucky with not getting burned. There's also the issue with BTRFS performance degrading hugely with any significant fragmentation, to the point that "autodefrag" has to be a feature, which of course also adds SSD wear... ZFS has never burned me.
