"There were about 370,000 nodes in past, but now it's only about 5000 nodes because blockchain is big
In future, i think there'll less nodes, but all of them are very powerful"

Is not a problem that the verify of transaction go in the hands of a "few" of person?

There wasn't actually that much node. It was a bug with the crawler and Bitcoin wasn't even that popular at that time.

The early December 2013 network snapshots, i.e. with over 100k nodes, are not valid as the crawler at that time took several hours just to complete one full network snapshot and it includes all nodes from addr responses which can be faked or likely stale. Those snapshots were linked to from getaddr.bitnodes.io/SNAPSHOT_NUMBER/ which have been removed since.

With the new crawler released in late Dec 2013, the crawl time was brought down significantly down to sub 5 minutes with considerably good churn rate. I use the churn rate to measure how good a network snapshot is. A value of 0 implies the network snapshot was taken instantly but of course that's not possible. At the moment, we are seeing a typical churn rate of 30+: https://getaddr.bitnodes.io/nodes/

Bitcoin does need more geographically distributed and stable node. Powerful nodes isn't a must. In the future, Block pruning would still allow the relay of TX which eliminates the problem of verifying transactions but it won't relay blocks. From what I understand, this would be a problem for SPV clients and they would rely on trusting miners even more.

thats an april fools joke.

the fool made like 1 page of valid addresses and then the other hundreds of pages are keys that are random and dont match.. in short it was a joke to scare people, and it looks like you fell for it

I didn't fell without a reason! somone had found some cents on directory.io Proof? https://bitcointalk.org/index.php?topic=1194333.msg12544561#msg12544561

I would still consider it as a joke. That is merely several cents and it could just be placed there by people who want to troll.
