There's that. OTOH if this is super common for crypto, I'm thinking we
should design it in and make it convenient in the input syntax to make such
transfers.

In theory it *could* be done with a plugin today as Ben suggest: I imagined
it more like this though:

2020-12-19 T "Binance" "Transfer BTC Coinbase-Pro => Binance"
Assets:Crypto:BTC:Binance 0.2 BTC {}
Assets:Crypto:BTC:Coinbase-Pro

whereby the plugin would know to select transactions with flag 'T' (or
perhaps a tag given in its config, whatever) and convert the posting on
Assets:Crypto:BTC:Coinbase-Pro to include all the original matched
reductions. I think this should be doable today actually.

beancount.ops.holdings is gone in v3. It was superfluous anyway (well when
I started it I wasn't sure if it would start acquiring more features than
just an inventory). Now you can simply aggregate over an inventory and
enumerate its contents (positions).
