Here is a calculation for OG OpenSea Wallets: OG wallet activity netted OpenSea roughly $900m (lets round up for $1b to make it easier) Its been estimated that OG activity will get 10% of $Sea supply (100m tokens at a 1b supply). $1b fees generated for 100m tokens. Means for every $10 in fees (every $10 you made OpenSea), you will get 1 $sea. $10,000 = 1,000 $SEA $1b FDV = $1.00 per token (IF OG activity gets 20%, that allocation is doubled, if they only get 5% that allocation halved)

Plus maybe a few multipliers based on overall volume, days on platform, different number of unique transactions.
