On deep thinking about the full market movement,it will be the true one.Because the price of Luna was reduced 99.9% from the old value.This give huge impacts to the market.Many people had cash out their entire money from the Luna.Some people had withdrew entire and get the funds out to their bank accounts.It was reasons for the dump.
The effect of a 99% decline in luna prices is very bad for the crypto market, a lot of people's speculation about the bear market today is related to the price loss factor on luna and ust coins, I think not all traders cash out of losses but they will recover losses on bitcoin trading and other top altcoins.
