Looking at historic data like the rainbow chart, bitcoin dominance, total market cap and number of coins/tokens in the crypto world, I'd say the bear and bull markets coming will be substantially different from the past.

Let's look at some charts.

My analysis:

• Rainbow chart: Given the dispersion of projects and retail, it is likely bitcoin chart won't touch the red zone nor the blue. Will be more stable.
• Dominance chart: Normally after a low BTC dominance comes a bear market. That was before binance (and BNB), before Cryptodotcom (and CRO) and before many game changing projects. Latest BTC dominance before a bear market was 40 in January 2018. Think next bear market won't come before BTC dominance reached 20 or so.
• Market cap: Last bear market brought the market cap down from 900M to 150M USD. Next one will probably bring the market cap down from 5T to 1 T USD. It means that we won't see our portfolio lowering more than 50% from what we have today if we didn't take too much risk.
• Number of projects: This is where I think we will have a substantial correction and a lot of non sense out there will have to disappear.

Conclusion:

We shall remain bullish!
