Though a lot of people were initially doubting if Bitcoin price will be able to reach $150k but many experts had already predicted that it it's very likely hot that landmark before the end of the year and for experts to make such predictions, I believe they've already made very deep analysis of the market. Again, the recent widespread adoption of Bitcoin especially from governmental bodies in different countries including the country with the largest economy in the world is a strong reason for us not to doubt the possibility of $150k.

Now, to your question about if more countries will be legalizing Bitcoin, I think the answer is yes. Rising prices in most cases increases public interest, boost adoption and highlight Bitcoin's economic potentials especially to countries facing inflation, currency devaluation and other economic issues that Bitcoin brings solutions to. More government are now very likely to legalize Bitcoin as a means of attracting innovation as well as staying competitive in the evolving global digital economy.

Bitcoin's decentralization have always been the major reasons most governments are yet to legalize Bitcoin as it strips them the power to control but with the success Bitcoin have recorded already and the potentials it promises, most of them will be left with no option than to join the Bitcoin movement or be left out in the digital financial system.
