Liquidity: Liquidity in the crypto market refers to how easily an asset can be bought or sold without affecting its price. High liquidity is desirable as it generally means there is a more active market for the cryptocurrency.  

Long/Long Position: In trading, taking a "long" position means buying a cryptocurrency with the expectation that its price will increase over time. It's essentially a bet that the value of the asset will rise.  

Lightning Network: The Lightning Network is a second-layer scaling solution for blockchain networks, such as Bitcoin. It aims to enable faster and cheaper transactions by creating off-chain payment channels, reducing the load on the main blockchain. 

Layer 1: In the context of cryptocurrency, "Layer 1" typically refers to the underlying blockchain protocol or network itself. It represents the fundamental layer of the technology stack and includes the core features and consensus mechanisms that enable the creation and validation of blocks containing transactions. Examples of Layer 1 blockchain networks include Bitcoin and Ethereum. Enhancements and scalability solutions often target improvements at the Layer 1 level to optimize security, decentralization, and overall network performance. 

Layer 2: In the realm of cryptocurrency, "Layer 2" refers to secondary scaling solutions built on top of a base blockchain (Layer 1) to improve transaction speed and reduce fees. Layer 2 solutions aim to enhance scalability and usability by handling transactions off-chain or through sidechains, while still relying on the security of the underlying Layer 1 blockchain. Examples of Layer 2 solutions include Lightning Network for Bitcoin and various scaling solutions for Ethereum, such as Optimistic Rollups and zk-rollups.
