Agree. It's relatively hard to establish a Bitcoin node, or use the cryptocurrency to its full potential within these countries. This applies specially to China, as it's one of the most restrictive countries in the world. Despite some governments being picky about crypto and Blockchain tech in general, they've seem to be changing their stance recently. This is because they've been studying/researching how Blockchain technology works and how it could benefit them in the future. Once they get the "hang of it", I'm sure that they'll be more open to crypto and Blockchain within the long term.
Right now, I would prefer most countries within the EU as they're more open to crypto than the US itself. A good example of this is the island of Malta which is extremely friendly towards crypto. Even Binance has established its operations there, as the country has very friendly regulations for crypto startups and companies. Despite this, other countries could improve their regulatory-stance over crypto as they study the trend more deeply. The US, being one of the most powerful countries in the world, has had a large impact on crypto's growth within the mainstream world. If it becomes extremely friendly towards crypto, it could prove to be highly beneficial for the Blockchain industry.
Nonetheless, there are more countries that are friendly towards crypto than we've thought there would be. Most countries within Asia and America have already opened their doors towards the growth and longevity of the Blockchain industry in general. It should only be a matter of time, before restrictive countries like India change their mind as they accept crypto as a legal form of payment. In short, countries like Japan, Malta, Singapore, US, and South Korea seem to be the most friendly ones towards crypto within the mainstream world. Just my opinion
