I am very skeptical of those price predictions.
Also, price predictions are off topic to this thread.
If banks knew about bitcoin, they would be full of bitcoins. Instead they do not know anything and they hold cash.
The launch of Bitcoin Spot ETF in the United States and other countries will result in a large amount of capital flowing into Bitcoin. Also, as banks reduce interest rates, investors will look for stable income, and they will look for the most reliable and safe shares. Then they will come across shares of various Bitcoin-based companies from which investors are currently earning good profits. As a result, more money will flow into Bitcoin. Again, due to the current high inflation, fiat currency is losing its value day by day, so people will stop holding fiat currency, as a result of which some of this money may flow into Bitcoin. Also, due to the technological development of Bitcoin, Lightning Network, Ordinals, Layer-2, the security of Bitcoin has been strengthened, so Bitcoin is gaining acceptance among people. Considering all these things, it can be pretty sure that the price of Bitcoin will increase in the future, but it can never be said for sure when, after how long, or by how much. Loyang mentioned that Bitcoin could increase by 50% in the next 12 months. Yes, it could. If Bitcoin-based companies can reach their specific targets and hold Bitcoins for a long time and various countries start using Bitcoin as a reserve asset due to negative attitudes towards Bitcoin, then its price could increase much more during this period.
