If we mirror this event of November 2013 to March 2017 over what the market is experiencing in 2018, you will get a classical perspective to this bear market. Yes, the market is definitely larger than it was 45 years ago, but the fundamentals remain the same. I dont think the drop will be up to 90% (I think 70% is fair enough) but it could drop lower. One thing I am certain of is that this bear market is not ending anytime soon. If it took about 40 months to get back to the all time high in the previous bear market, it might take at least a quarter of that for this market to get back at the level we all cheered about. Personally, I have set my mind to January 2019. Not necessarily to see bitcoin at $20k, but to see the bulls take over fully. It could take longer, but this bear market shouldnt last up to 20 months.
This is the time for the hype to die down and real information to gain more ground. There is blood on the streets, so it is definitely a good time to buy. However, it matters what you buy. I am definitely not selling any serious stakes in my crypto assets for now. And I can hold on for as long as I want. That is the real definition of money you can afford to lose. In the real sense of it, nobody has money they want to throw away. But if you have to sell in 6 months or less, you are not playing smart.
The key to winning in trading and investing is to buy low and sell high. If you cant wait for forever, you will buy high and sell low. The last time it was 4 years, lets hope its below 2 years (or much less) before $20k again. Just to keep in perspective, we are still 4 months in on this bear market. Brace up!
