Ethereum is the only longterm hold I would suggest. Bitcoin is obvious too. Other than that, I wouldn't have any other long term holds in my portfolio. I would wait it out and see which ones are gonna make it out. A few obvious ones like BNB, and Solana probably will but how many others?
For Ethereum and Binance coins it will be clearer to increase again when Bitcoin starts to recover within a certain period of time because the two coins are still very often following the flow of Bitcoin movements as well as several other coins such as Matic, Cardano, Solana and others.
