Yes.


That video probably used bitnodes.io to verify his node actually can accept incoming connection.


It's not latest version of Bitcoin Core, but you won't face problem running older version.


What do you mean by update? If you mean network upgrade (such as SegWit addition), you're not required to upgrade version of Bitcoin Core. But you'll miss feature and functionality related with the network update.

OP I think you or the person who has lost the funds should be more careful, although this claim of yours needs a little proof so please show that also to confirm whether you are saying true or not, and how did you lose the funds I mean did someone stole the keys, or you forget the keys and don't have any access to your funds now?

And is it was 4 to 5 million dollars worth of BTC! as your statement indicates as they are 4 to 5 million BTC which got lost not the 4 to 5 million dollars worth of BTC. I just searched on Google and it says that now a total of 3.7 million BTC have been lost out of 19.6 million circulating supply (Article is 2+ months old--> Source
That's why I love Satoshi hehe, He has swag.

All the lost Bitcoin only mean a lower maximum supply. That causes the vaue of Bitcoin to go up. Less supply and more demand is just what we need. In fact, this will continue happening and Bitcoin value will continue rising. There is absolutely nothing wrong with this. Think of it this way: If a Bitcoiner loses his coins because they died or lost access to their wallet, all hodlers receive a kind of inheritence, automatically.

Is that not a great thing?

We should not change anything about this.

So that thieves (who are not the actual owners of the coins) should be claiming lost coins?

They should prove with their private keys that they are the owners.

You can not know the exact number of bitcoin that are lost because you can not say all coins that are not moved to another address are lost. Or which methodology did you use to arrive at 4 to 6 million BTC to have been lost?
