Incentivized testnet

During the incentivized tests before going public launch, all participants are usually rewarded with tokens that will have economic value upon launch.
This is the list of the popular incentivized testnets of 2020 in which I’ve participated:

• Cardano – Shelley’s testnet
• Polkadot – Kusama
• Cosmos – Game of Zones
• Matic – Counter Stake
• Elrond – Battle of Nodes
• Near – Stake wars
• Coda – Genesis
• Solana – Tour de Sol
