Recently, Binance announced that Signature Bank would not support any cryptocurrency transaction of less than $100k. This would be effective from February 1 and for every Signature’s crypto exchange client. Therefore, some people won’t be able to use SWIFT bank transfers to purchase or sell digital assets for smaller amounts. 

Binance said that 0.01% of average monthly users were directly using the service of the Signature Bank. Also, the company is actively working on coming up with an alternative solution. But the users can use their accounts for buying and selling cryptocurrencies using fiat, credit, or debit cards.
