In the same way that AI revolutionized content creation, Edgefolio is revolutionizing DeFi profitability 
by way of automated and managed distribution. Large institutional fund managers make it near impossible 
for the average crypto investor to benefit from fund appreciation due to high entry barriers and long-term investment approaches
in blue-chip coins. Edgefolio and the introduction of EdgeFund marks the beginning of a new age for DeFi profit sharing
that provides regular ETH dividends to NFT and Token holders.
