The longest Duration of a bear market is still the 2013 to 2015.
The current bear market is only 396 days in from ATH.
So with said, and the fundamentals are only getting better and also keeping in mind that BTC has seen a bottom in conjunction with 8 to 12 months out from halving.
I think the odds of crypto making a higher high in mid to late 2019 is very good.
As you can see from the chart above, after the downturn, the spikes of volatility get less and less which then starts to form a base.
The next thing that happens is the higher low's
This has been by far my best indicator for all types of trading to make money on.
It's also what i will be looking for this year on crypto chart for the entry.
