Depends on your time frame and what you're buying in with surely. Putting fiat into the market right now is clearly very risky, but when it comes to Bitcoin value it's been flat for days with no changes (no trade zone mainly) and against Ethereum is still very trade-able (recently bought ADA was great idea).
If you're still hodling shitcoins like usd, eur, gbp, etc, then no doubt they are getting a bit of a dead cat bounce, and could bounce a bit higher, so better to sell at higher levels imo. Anything down 80-90% over the past year and in a strong down trend is due to see a bit of rebound before going lower

On a Weekly scale Bitcoin dominance is still in a strong downtrend, waiting to break-down so remains very invest-able with BTC/ETH imo:

The second month of a one year long bull market is no time to be getting scared, it's the time to be getting aggressive in positioning yourself personally. I see the break of Bitcoin dominance to 50% as measured by head & shoulders target as well as general multi-year fractal. The fundamental & logical idea of Bitcoin being only half of the crypto market as opposed to the majority doesn't even cross my mind to be honest, I just follow charts.
Also, I prefer this view. The "flip the chart upside down" version looking at the bullish reality long-term:

Biggest volume spike we've ever seen this week so far diversifying into alts? Looks great.
CMF looks great. RSI looks fine.
If you're already mainly holding Ethereum and haven't been diversifying recently you've been doing it wrong though
