Buying ethereum is not only at a time of correction, for now I think it's also the right time to buy ethereum, but after you buy it now you have to make sales targets to get profits. means you have to determine the sales method yourself.
BNB has a safe level of investment for now, but there are several other coins in my view that are good, namely BNB and the big 5 coins on the marketcap, the coins are still in the cheap category and have good market movements, especially when there is a pump for bitcoin, the coins will also follow themselves, even the top 5 marketcap coins are suitable for long-term investments compared to investments in other coins.
It's too general as an explanation. You should be able to clearly suggest what type of coin is the most suitable to choose. BNB is currently a safe type of coin for investment, but other coins such as Solana are also on the safe list for investment.
