Bellscoin (BEL) is not a new crypto, it has started as a Scrypt coin based on the currency from the Nintendo game Animal Crossing a few months ago, but the project was abandoned, however just recently it was relaunched with new developers and has already generated quite a lot of community attention, so you might want to take a look at it now that it is already getting added on exchanges.
In the Animal Crossing universe, Bells are the primary form of currency. To gather them, you must collect fruits, catch bugs, fish, dig for fossils, etc. and trade those items for Bells. In the crypto world, we just mine for them!
The Bell amount you get from the various items is quite random, so Bells as a cryptocurrency has random rewards in various denominations as well.
