My current $BTC analysis. We are in the band of 60K-68K and 68k-74K. There is a strong resistance at 84K level. I don't expect a new ATH any soon, it would really surprise me if it did. In the down side, 59K and 53K are the support levels. My prediction from this is that, the BTC will go 53K - 56K, even if it's a spike, it will do that. It is currently overbought. Check the green candlebars at the monthly graph. Will it continue all green like this? I seriously doubt that. It is against the market dynamics.
The most altcoins will follow BTC. (such as $PEPE $FET etc. etc.)
This doesn't mean you need to be in all cash. I share buy signals with my followers. There are also ways to win in sideways market.
