According to @PolynomialFi, traders are challenged to build a $7 crypto portfolio from a fixed menu priced at $3, $2, and $1 tiers: Bitcoin BTC $3, Ethereum ETH $3, USDC $3; Solana $2, Doge $2, Hyperliquid $2, Fartcoin $2, Aster $2; Plasma $1, BNB $1, WLFI $1, Uniswap $1, Aave $1, Ethena $1, source: @PolynomialFi. Under these constraints, a concentrated BTC-ETH mix could be BTC $3 + ETH $3 + BNB $1 = $7, source: @PolynomialFi. For broader exposure, examples include BTC $3 + Solana $2 + Uniswap $1 + Aave $1 = $7 and ETH $3 + Solana $2 + BNB $1 + Ethena $1 = $7, source: @PolynomialFi. An allocation that includes USDC from the list is USDC $3 + ETH $3 + Aave $1 = $7, source: @PolynomialFi. These mixes strictly follow the asset list and price tags provided in the post, allowing traders to balance concentration versus breadth within the stated $7 budget, source: @PolynomialFi.
