I've been through 2018 too, I'm not saying it won't happen again but by comparison the market is very different now. So it is very difficult for BTC to drop to 10k$ and ETH to 300$.
I have the same thought but don't close your doors that everything is possible in this market. No one has seen what has happened to Luna before it actually happens.
I've seen 2018 for Ethereum and luckily, I got some from that time and sold it last year.
It's unknown whether it will be back there to its old price or not but just consider that everything is possible for any coin. @OP if I have any extra budget now, I'll buy.
