The news: Traditional payment providers are deepening their involvement in the cryptocurrency sector. Mastercard will buy stablecoin startup BVNK for $1.8 billion, per a press release. The network tried to buy BVNK in October for about $2 billion, but the deal fell through. (Mastercard then tried to buy Zerohash, conveniently also for $2 billion, but that deal also fell through.) Wells Fargo applied to trademark “WFUSD,” per filing records found by Decrypt.
