I like the points you made OP. Because I also think that Bitcoin can help refugees or anyone who wants to flee or leave their country which is experiencing a humanitarian crisis or is at war. Carrying cash in person may be very dangerous. So converting it to Bitcoin will indeed be much safer. Because control is completely in our hands. Apart from that, with Bitcoin it will also be easier for us to access it as long as there is internet. Especially if the banks are closed. So as long as we can transfer money from our bank account digitally, we can convert it to bitcoin. But we also have to make sure that we use a safe wallet. And have stored the private key safely.
I mean by logic it's true that you can take everything with you online, like you do not even need a hardware, just need one email, and an account at an exchange, you can go to anywhere in the world and you can open the account there.
However, I do not think that people who are at refugee levels have the extraordinary amount of money that they would normally have to carry somewhere else to begin with. Imagine people in Gaza right now, Israel is attacking, and surely there are terrorists there but lets be reasonable and acknowledge that there are innocent people there too, who are getting their city bombarded constantly.
So let's assume you want to leave, you come from a nation that has nothing, even water and electricity is given by your enemy, and you basically have your clothes on your back that could be considered all you have, what good does bitcoin could do for you? What are you going to carry towards another nation if you could even leave?
I think it is regarding refugees that are from nations that is not currently in a war. I mean technically speaking tons of people move to USA every year, legally or even illegally, mostly via Mexico but the majority of the people who are illegally in USA are people who overstayed their visa rights, given 6 months, been there for 9 months for example, that is the majority of the people.
I think it should be important to note that we are not going to end up with anything that would prevent those people. Lets assume you are a Mexican, and want to illegally immigrate to USA , you can definitely sell everything you own, whatever we are talking about, anything that doesn't fit your backpack, and then use that money to buy bitcoin and then when you are cross the border you are done.
