Should BTC follow a similar drop to the 2013 bubble we will be looking at newer lows. There are many similar price drops based on percentages from the 2013 bubble; both have already dropped -40%, -50%, and -70% in order at their respective price dips. The one noticeable difference i could see is that the 2018 bubble seems to be running at a faster pace (2-3 times faster)... so if there is a bear market, maybe it won't be 2 years but rather 1 year or less. Good luck, this is not investment advice.
