TradeBOOST is what we call selling an “out-the-money, European, covered option”. This means the seller collects a non-refundable Instant Premium in return for selling the right (not an obligation) to trade a particular digital asset at the end of a specified period for a specified strike price. As TradeBOOST is a covered option, this means the seller would need to pledge 100% of the underlying digital asset. It is the ideal instrument to monetize digital assets when the market is quiet or if you have a longer-term view with short-term expenses to fulfill.
TLDR: You collect Instant Premium to sell a right to trade.
