In this paper we aimed to examine the profitability of technical trading rules in the Bitcoin market by using trend-following and mean-reverting strategies. We applied our strategies on the Bitcoin price series sampled both at 5-min intervals and on a daily basis, during the period 1 January 2012 to 20 August 2019. Our findings suggest that, overall, trading on daily data is more profitable than going intraday. Furthermore, we concluded that the Buy and Hold strategy outperforms the examined alternatives on an intraday basis, while Simple Moving Averages yield the best performances when dealing with daily data.
We investigate the relationships of the VIX with US and BRIC markets. In detail, we pick up the analysis from the point left off by , and we focus on the period: Jan 2007 -Feb 2018, thus capturing the relations before, during and after the 2008 financial crisis. Results pinpoint frequent structural breaks in the VIX and suggest an enhancement around 2008 of the fear transmission in response to negative market moves; largely depending on overlaps in trading hours, this has become even stronger post-crisis for the US, while for BRIC countries has gone back towards pre-crisis levels.
