Different ways to stake cryptocurrencies:
1. Staking as Validators: This process involves staking native tokens and running your own hardware to validate transactions.
To become a validator on Ethereum2 which is PoS network, you need to stake 32 ETH.
2. Staking as a service: If you are uncomfortable with running your own hardware and software stack, you can deposit 32ETH in Ethereum or the equivalent amount for a different network with a service provider who can run the stack for you in exchange for a portion of staking earnings.
3. Pooled Staking or Liquid Staking: There are DeFi protocols that act as a matchmaker between liquidity providers and entities that can run validation nodes. Your tokens get added to a pool that are then used for running validation nodes. In exchange for providing liquidity, you receive Liquidity Provider Tokens.
4. Centralized Exchanges: Users can stake their crypto via centralized poolscreated by centralized exchanges. However, it involves giving up custody of funds.
Staking requires locking up crypto tokens on the network for a fixed period of time.
