The Binance Earn program is about lending to short-sellers.

Short-sellers borrow a coin, sell it, buy it back at a lower price, then repay the coins with interest.

Of course when the price is low shorting vanishes and the interest paid drops.

The impetus for Hive's price dropping is whales flocking to Binance to lend to short sellers.

Do what the BitcoinCash community is doing - withdraw coins from the exchanges to make short-selling difficult.
