A large market cap does not mean the same kind of staking. Bitcoin has no protocol staking. Ethereum and Solana do lock coins for validation. Comparing only the rate on a product page erases that difference.
Bitcoin
Miners produce blocks under proof of work. There is no protocol interest for locking coins. 폴리젠's BTC product locks an amount for a term and adds coins at the rate quoted when you apply. It is a platform product. The market is the deepest and the rate is on the low side of the five assets, which fits a long hold where you want the coin count to grow slowly.
Ethereum
Ethereum has used proof of stake since 2022. Validators deposit ETH and propose or attest to blocks. Doing it yourself takes 32 ETH and a server that stays online. A wide ecosystem means many uses, not a calm price. Deposits are Ethereum mainnet only. ETH on another layer-2 network is a different transfer.
Solana
Solana adds Proof of History to proof of stake so validators can order transactions quickly. Delegating SOL shares a validator's rewards, and undelegating has a waiting period. The reward rate is high and the price swings are large. Splitting maturities leaves more liquidity than putting the full balance on the longest term.
One way to split roles
There is no correct percentage. Assigning a job to each asset avoids a portfolio that only follows the rate ranking.
- Core long-term holding: keep a BTC weight and accept the lower rate.
- If you also care about where the network is used: put ETH in the middle.
- If coin-count growth comes first: use SOL or POL for only part of the balance, on split terms.
What to leave out of the comparison
Today's fiat reward leans on today's price. Compare annualized rate, the inability to sell during the lock, the deposit network, and whether that network has protocol staking. Leave the price direction outside that table.
