Bitcoin (BTC) dropped over 8% in the past 24 hours to sink below $21,000 for the first time in seven weeks as investors continued to fret about the fallout from crypto-friendly bank Silvergate Bankrs implosion.

On Wednesday Silvergate Capital (SI), the parent company of the lending focused bank, said that Silvergate Bank would lvoluntarily liquidater its assets and shutter operations.

The largest cryptocurrency by market capitalization traded as low as $20,050 on Thursday, its lowest level since Jan. 14, before regaining some ground to hover just over $20,250.

lThis remains a tough environment for crypto given the fallout from Silvergate Capital, so bitcoin could see further selling pressure test the $20,000 level,r Edward Moya, senior market analyst at foreign exchange market maker Oanda, wrote in a Thursday note.

In the past 24 hours, bitcoin posted more than $60 million in liquidations, with over 95% of them being long positions, Coinglass data shows.

Investors became concerned and bitcoinrs price started dropping when last week when Silvergate said that it had delayed filing its annual report and warned of its potential inability to continue as a lgoing concern.r

Moya wrote that Silvergate Bankrs shutdown underscored crypto bankingrs ongoing problems. He added that lthe cryptoverse now tries to find a new services company to help make payments and other deposit-related services.r

Julius de Kempenaer, senior technical analyst at StockCharts.com, noted in an email to CoinDesk that if more service suppliers to the crypto market like Silvergate fall into trouble, it will lmake getting access to crypto harder and h not be very inviting for new investors.r

Stefan Rust, CEO of economic data-aggregator Truflation, wrote in an email to CoinDesk that Silvergaters crisis will slow the rate of institutions entering the market because lthey don't have an on- and off-ramp that scales as fast."

lIt will also push more crypto business offshore,r Rust wrote. lMost, though, will find another on- and off-ramp that they can use to work around this.r
