I'm trying to fill my bag with projects built on Polkadot so I'm just researching now which coins I should consider and follow.
Thoughts?
Energy Web Token (EWT) - If you look at early Polkadot documentation they describe the possibility for Energy Web to run a relay chain... not a parachain... a relay chain. This along with all of it's partners and projects makes it top cotender imo. However note that they stated they won't launch a relay chain until it's needed.. they're not going to build it for hype, only for utility. Hint: they're going to need something to scale.
OCEAN - Data marketplaces are a new asset class. Not much else to say OCEAN will be huge.
Robonomiic (XRT) - Millions of IoT devices are going to need a mechanism for trust, communication and data transmission.
Dark Dot (D4RK) - Chains can always benefit from privacy whether for tx, mixing, data storage, e-commerce or things we haven't yet thought of. This low cap will offer interop privacy services in DOT ecosystem.
