You can mock this warning, but a massive wave of selling pressure will hit all cryptos before and towards the end of Oct. due to all exchanges closing in China (Chinese must sell to get out before they close) and all crypto-trading will be banned in China on Nov.1 onward.
This means the largest buying-block of cryptos (the Chinese) will be removed from the Bitcoin market on Nov.1 onward. China ended Bitcoin's party and their Gov't will block IP addresses from trading cryptos outside of China on other exchanges. You can google to verify this news.
With that, if you always wanted to buy Bitcoin for under $1000 this year, you may be able to do so on or before Oct.31 and you can thank the Chinese Gov't for it. This will also cause Litecoin, Ethereum, Ripple XRP and the Altcoins to also crash down too towards the end of Oct.
Don't care either way as never owned Bitcoin. Simply giving you heads up.
