say: you can do better/ you can buy low and sell high; you don't need buy and hold forever.
so the first 10%草根大众 do earn small money by acting quickly
the follower 80% 草根大众 do lose money
and the reset 10% 草根大众 buy and hold forever earn the market return.
this is for stock market
for housing market because it is hard to liquidate.
so maybe
70% 草根大众 will buy and sell
30% 草根大众 will hold forever [for exchange primary residency)
because of the liquidity it is easier to 调戏 common stock market.

if sheep goat zebra united together lions can do nothing.
草根大众 shall buy and hold forever!
