  Bitcoin has emerged as a fascinating phenomenon of the financial markets.
Without any central authority issuing the currency, it has been associated with

a potential influence of the Chinese market. The evolution of the relationships
is examined in both time and frequency domains utilizing the continuous
wavelets framework so that we comment on development of the interconnections in
time but we can also distinguish between short-term and long-term connections.
