I'll be stacking a for a bit before buying one in that case; if push comes to shove and I lose faith in BCH the way I (justifiably) lost faith in every other cryptocurrency that's not a privacy coin, it'll be easy to swap it back for Bitcoin and flash Bitcoin-only software (although at that point upgrading is mostly redundant).

My only other use case for BCH is Memo, haven't really used anything like read.cash because I (barely) use Substack.
