Crypto’s Black Monday continues to wreak havoc. Changpeng Zhao, the CEO of crypto exchange Binance, tweeted that there would be a temporary pause on Bitcoin (BTC) withdrawals.

Temporary pause of $BTC withdrawals on #Binance due to a stuck transaction causing a backlog. Should be fixed in ~30 minutes. Will update.

Funds are SAFU.

— CZ Binance (@cz_binance) June 13, 2022

CZ, who often lends his opinion to projects and the market, regularly tweets on behalf of Binance to his 6.4 million followers. He quickly updated the tweet to show: 
This is only impacting the Bitcoin network. You can still withdraw Bitcoin on other networks like BEP-20.
SAFU is a meme that plays on the word ‘safe,’ first appearing in a Youtube video three years ago, while it also refers to Binance’s trading protection fund, the Secure Asset Fund for Users (SAFU). The fund was built during the previous bear market, but in light of Celsius’ apparent insolvency, investors may be right to raise the alarm.
In a follow-up tweet, the exchange setback may be worse than first thought:
“Likely this is going to take a bit longer to fix than my initial estimate. More updates soon. Thanks for your patience and understanding.”
Binance official Twitter account confirmed the delay, suggesting that the issue was due to a “stuck on-chain transaction.” For some commentators, the Lightning Network on Bitcoin would have avoided such an issue.

Indeed, despite Binance’s size and global presence, it has yet to keep up with its competitors regarding Lightning integration. Sam Bankman-Fried, head of competitor FTX exchange recently tweeted he would encourage developers to work on integrating the layer-2 protocol into the exchange but Coinbase and Binance lag behind.
Kraken also recently allowed its customers to withdraw funds from accounts instantly, using the LN. In welcome, positive news, the total number of Bitcoin on the network recently crossed the 4,000 BTC milestone.
