i am new to following bitcoin is something like this part of the drop in price today. Or is todays drop normal?
there is nothing "normal' in terms of bitcoin volitity. usd and other currencies shift at most 1-2? in the short term bitcoin can do big jumps.
go to sites like coindesk and look at the price charts eg in 2 days in january it went from $267 to $177 and a day later back to $210.

Today's drop was more than normal, compared to daily prices changes in the past few months. Yesterday IIRC the peak was about $295 USD, and now a coin is selling for about $255 USD, which translates to a 15% drop in less than 24 hours.
