I'm trying to understand tokens, but I'm not really getting it. Do any of these *do* anything, or is it just a bunch of unique identifiers that have no specific purpose as of now.
Those are "equity tokens." I think the bigger future is in "utility tokens" as something similar to discounted gift card balances with ecommerce platforms.
Tokens basically just give people the ability to create their own currency on top of the bch blockchain. Read through https://simpleledger.cash/ if you haven't already
