RE: New Year With New HOPE for Crypto!

If you have the general idea of derivatives then just replace the value of underlying assets such as bonds, and stocks with any cryptocurrency such as BTC or ETH, then this will be a crypto derivative! But the overall idea is not so easy to explain, but in short, it means the value of something which is used for a contract between the seller and buyer at a certain period of time.
