When they come here and see they'll actually have to invest in quality content...you're going to get people who leave because they don't want to. They want something they can buy and hold for a few days, then sell and the Steem cryptocurrency isn't moving the ways others are

Investors are not usually make-money-quick daytraders. Investors usually HODL. They don't have to produce quality content here. They can buy steem, convert to SP, and then delegate to some curation trail like steemSTEM or curie, and make passive income from the curation rewards in addition to the price of steem itself going up. If we include content creation, I've just listed 3 ways to make money here, and that's 2 more than with most other cryptocurrencies.

I can't even offload the SBD I have accumulated. I'm going to try to use Blocktrades to send SBD to Binance, but I'll have to convert it to Litecoin first because Binance doesn't have Steem or SBD. I'll probably have to take a hit in value though.

Bummer. I see you're sitting on 600 euro worth of SBD right now! Don't you know someone on steemit who has a bittrex account already and who you can trust to help you out? You could sent the SBD to them with no charge, they'll send it to their bittrex, exchange for bitcoin, then exchange for litecoin or something that has lower transfer fees, and then send to your litecoin or whatever wallet.
