How come an article dated 26th of September 2018 holds any value now? Also for the future reference, bitcoin's price has no relation with the Fed interest rate. US is already facing a trouble like shutdown and on the verge of seeing another emergency period.
If that happens, you may see a spike in crypto prices instead of a declining trend because a lot of people would want to safeguard their wealth by bypassing them into non fiat channels. I see no reason for worry in case Fed increases rate again in future which is most unlikely to happen.
