Investing in Bitcoin is still a smart choice but I do not know about Ethereum because it has refused to scale even with the launch of 2.0 even though it hasn't gone live fully, yet. If you go ahead and invest in Bitcoin, don't forget that you're essentially buying the top at this current prices so do keep funds in stablecoins or USD which you can use in buying back bitcoin in case it dumps in the near future. Ideally, you would need to keep buying lower to average down your entry price.
