You received 400,000 UNI. You didn't get that from airdropped but accumulated it. I'm about to trade it too but I'm having 2nd thoughts for it just started, tradingview chart won't even display any indicators to it so I'm just holding on. I'm interested to know how much dividends I will get upon staking it.
You cannot earn UNI by staking UNI.. But you can earn UNI by providing liquidity on Uniswap to 4 different pools for the next 59 days.

Liquidity MiningAn initial liquidity mining program will go live September 18 2020 12:00am UTC. The initial program will run until November 17 2020 12:00am UTC and target the following four pools on Uniswap v2:
ETH/USDT
ETH/USDC
ETH/DAI
ETH/WBTC
5,000,000 UNI will be allocated per pool to LPs proportional to liquidity, which roughly translates to:
83,333.33 UNI per pool per day
13.5 UNI UNI per pool per block
These UNI are not subject to vesting or lock up.
After 30 days, governance will reach its vesting cliff and Uniswap governance will control all UNI vested to the Uniswap treasury. At this point, governance can vote to allocate UNI towards grants, strategic partnerships, governance initiatives, additional liquidity mining pools, and other programs.
