Earlier
this
year,
the
Bank
of
Nigeria
Governor
Olayemi
Cardoso
said
crypto
exchange
Binance
had
allowed
$26
billion
of
funds
to
leave
the
country
untraceably
last
year,
hitting
tax
revenues.
That
kicked
off
a
series
of
events
that
resulted
in
the
detention
of
Tigran
Gambaryan,
a
U.S.
citizen
and
a
Binance
official,
who
had
been
invited
to
the
country
for
talks
about
the
dispute.
