What i said its a nature of bitcoin or should i say nature of all crypto and digital currencies.But there's an other feature if the price fall it will increase double. All the thing start happening in the begin of January and if you talk about its decreasing its just 2 months past.There's still 10 months left and its to much early to say such thing. Better to invest more its a right time, or you feel regret when the bitcoin breaks their records.
