Shrimp is a 1x METFI Multiplier and a Humpback is 10x.
You can start from as little as 100 USDT (Shrimp) and buy as much METFI as you want or buy higher NFTs that multiply METFI tokens faster. METFI tokens are always staked to your highest NFT so you always receive the correct METFI multiplier and you can upgrade NFTs at any time.
Every 6 months the multiplier base rate halves, slowing the rate of METFI token distribution and rewards that each NFT receives which makes METFI deflationary, scarcer, and more valuable over time, similar to Bitcoin.
The earlier you buy an NFT and the more METFI tokens that you stake to it the greater the benefits you receive.
The multiplier base rate began as 1 and halved to 0.5 in April 2023 and will halve again to 0.25 in October 2023 and so on for a maximum of 6 halvings with the final halving taking place in October 2025.
