If they had 700 bitcoin, it's enough for them to live like a king for the period if thousand years.And it with a conditions apply.Because we don't know, bitcoin will survive for that much years and can't be sure.Secondly he need to handover the control of bitcoin to next generation. If the handover missed out in any generation. Then everything everything get into soil.
I wouldn't be so sure about that part. I mean definitely a good amount, but who could hold it for a thousand years. I also believe that we probably won't see thousand years with the same nations. How many nations are out there with the same exact land they had a thousand years ago?
I do believe that they will keep on getting more and more in the end as well, it is just way too common for these type of big investors (even though El Salvador might be considered small nation, they are a big investor) they could totally gather more and more. This is why I believe that we should consider them getting thousands by few years time.
