As much as we wanted to be as the main source of payments, there are a lot of challenges that we have to face, like the volatility and not everyone are willing to accept it. Not sure what you mean by paper money disappearing though, central banks are not going to allow it.
For 2023, the prediction might still be the same, it could trade sideways for the whole year as we are still in the bear market.
So still we better prepared again, who knows, maybe there could be events like FTX that will make a huge impact on the price again and see another lowest for 2023 before eventually rising up next year. But with regards to Elon Musk, he has no influence on the bitcoin market.
I do not think that trading whole year sideways sounds that possible. I am not saying that it is impossible neither, but it's unlikely to say the least. People think 2022 was sideways but in reality it wasn't, we were a lot higher and dropped, it was a bear year and we dropped that's it, it wasn't sideway year. Sure most of the days were sideway but that doesn't mean that it will continue to be sideway forever.
I think it is clear that we are going to end up with profiting from upside movement this year, don't know how I know but it's just a feeling inside me saying that it's time to pick up some pace and go up finally, which will be awesome if it turns out to be true.
