I am a big supporter of blockchains that provide real usage value, other than through the crypo itself. The engine should be the blockchain, not the crypto.

However, I don't easily dismiss bitcoin for two, maybe three reasons:

1. it is a pioneer in this field
2. it has the largest adoption world-wide, by people not really interested in the particulars of the blockchains and
3. it has a well-chosen name (easier to market to the masses)
