Note how bitcoin has a more diverse economy (it generates attention output from more services), and how most services are not ubiquitous across networks -- each economy tends to be specialized on a certain type of attention product/service, at least during a period of time. While some of the relationships might be trivial (e.g. current users of a forked version of BTC such as Bitcoin ABC should gravitate easily to a new fork), others may encode useful investment information, such as crypto geo-political factors: users of Australian exchanges were more inclined towards BCH, over-the-counter investors in Canada remained mostly focused on BCT, Russians divided their attention.

## Macro case

### The fluid nature of attention

While hoarding for capital formation is a well-known fact in crypto economies, in terms of attention flows there can never be oversupply because at some attention price point there always will be a consumer. That is, the technologies of the old and new coins are close enough to ensure that users do not have to over-invest time and energy to take advantage of the opportunity — holders may even have access to “free money” if their wallets support both coins. But at the same time, the stock of interests from each community is unbalanced and separated enough so that there are points of attraction, where attention can flow by gravity.
That flux may also help explain why some minor altcoins that serve communities in which common interest is shared, resist dying: as long as there is attention flowing, some sort of passive or active transactional activity takes place. This activity may appear to obey mainly profit-seeking behavior (such as the miners’ capacity rebalancing towards a dominant chain right after a hard fork), but this is also just an expression of where the stream of attention first flowed.
Figure 5 shows attention inflows from one thousand services to the economies of bitcoin, bitcoincash, bitcoinxt, bitcoinunlimited and bitcoinclassic, and the flows in between those economies. Inflows are measured by incoming visits.
