There are always risks in business and if you want to make BIG gains then you'll have to take BIG risks too. In last few months, Bitcoin hasn't moved much up or down after the January's hype and dump. So I don't think engaging in Bitcoin puts us at any risk.
No one can generate profits consistently, Intermittent and extended losses are part of the trading game, for ex. a day trader may suffer eight loss making trades in a row and only recover with profit on ninth trade. to handle these risk, a day trader must have a sufficient cushion of capital, traders needs also a solid foundation of knowledge about how markets function.
