Data from Coin360 shows the largest cryptocurrency put an end to its sideways trading style on Wednesday, falling several hundred dollars in minutes.
Markets at first rejected a more precipitous fall, with some exchanges showing Bitcoin reversing at exactly $8,000.
At press time, those levels had given way again, under pressure while fluctuating below the $8,000 barrier on local lows of $7,930.
Bitcoin IRA will soon allow customers to lend their retirement assets for interest.
The firm, which provides digital asset individual retirement accounts (IRAs) is partnering with digital currency trader and lender Genesis Trading to offer interest on cryptocurrency and cash holdings that customers want to lend out, including bitcoin, ether, XRP, litecoin, and zcash.
The program will be launched in November with a limited number of participants on a first-come, first-served basis, and annual interest rates will vary based on lending coin and term length.
Bitcoin IRA declined to define a limit, but chief operating officer Chris Kline told CoinDesk that the firm aims to have the product available to anyone over the next six to seven months.
