Bitcoin seems to be not in a good shape nowadays. What do you think of that? Is it a good time to invest in cryptos or is it better to wait some time to see what will happen to them?
In what way is Bitcoin "not in a good shape nowadays"? It's been well over a decade since Bitcoin was released to the public and it's (mostly) the same as it has ever been. The crypto market is more robust than ever, despite the ongoing attacks by media outlets.
If you're referring to the FTX debacle, that was only one exchange that taught new players a very important lesson: don't trust centralized authorities.
