If you invest long term in top coins like Ethereum, BNB and some other coins I don't think you need to worry,
The downturn in the market is normal and there is no need to panic too much.
just keep an eye on the movement and development of the market
That's right, as long as the choice is on a good coin and the top coins rank there is no need to apply any worries to them because they will always improve when the market improves and they are also often quicker to find price fixes when the market starts to give a very good indication
