After Bitcoin's each big movements, there is something happen in South Korean. As if they are acting to decrease the Bitcoin price.
Bitcoin has nearly broken down the $10K resistance, government raided UPbit. UPbit is the largest exchange based on South Korea.
As usual Bitcoin's sharp down was effected alt coins. Even most of major alt coins were effected negatively such as Ripple, Eos, Cardano and IOTA. I checked my portfolio at Blockfolio, i just saw reds.
However, there is nothing to fear. Bitcoin rallies quickly and all other cryptocurrencies follow it. There is always easy gains for you in similar cases.
