I've posted about staking in some other thread. It's not just for Ethereum but also some of them have BNB.
Yes, staking is one thing we can do in times of market conditions like this to keep making a profit,
but then again not everyone can do that and they also need to consider,
Top altcoins like Ethereum, BNB, or Matic I think it's worth buying and suitable for long term investment
If you're for Ethereum, stakingrewards.com suggests top 10 staking providers.
1. Binance staking - custodial
2. Kraken - custodial
3. Bitcoin Suisse AG - custodial
4. Stake DAO - decentralized
5. StakeWise - decentralized
6. Guarda wallet - decentralized
7. ANKR - decentralized
8. MyCointainer - custodial
9. Cream Finance - custodial
10. Blox Staking - decentralized
You should understand that if you're fine for holding it, you should just hold it. But if you're also trying to make out from it while holding it, you can stake it but make sure that you choose the right platform and understand what custodial and non custodial means and as well as centralized and decentralized. Based on the info from the website, all of those altcoins that you've mentioned are supported in ANKR and MyCointainer.
