Stablecoin payments company BVNK is in early talks with investors for a new round of funding as interest in Stripe's corner of the cryptocurrency market grows following its landmark acquisition. The startup, backed by Tiger Global Management LLC, is in talks with potential backers with the goal of raising at least $50 million, according to people familiar with the talks.
