Yes! Steemit should advertise. I'm one of the few people that hated Bitconnect for the scam they were, never invested in it, but respected their marketing machine.
If a scam-coin like BCC could have been worth $300 at a point due to viral marketing, what could be the valuation of a real use case blockchain, with zero-fee, instant transactions and with best-in-industry scalability and capacity.
Yes! Steemit should advertise, but not on steemit.com. coinmarketcap would be a better place, or coindesk, sites like that.
