With the unpredictable changes in bitcoin price people have chose to hold instead of day trading,I mean the majority have.
How risky is day trading at the moment?
Right now volatility is pretty high when it comes to bitcoin and whenever there is higher volatility there is always a greater risk, however when there is higher volatility there is also the potential for greater rewards. As long as you are sensible with cutting your losses etc and not panicking you shouldn't ever lose a huge portion. By that I mean max 10-20%.
Volatile nature makes day trading quite tough. Instant decision is mandatory in day trading. Mostly instant decision leads to wrong destination ultimately. If you are not knowledgeable and wise enough, probability for losing is high. Thus day trading is highly risk.
