I think question should be Is Lightning Network safe? (not save)
Oh, my God! I've made such a ridiculous error, thank you! I've edited it.
I don't think all other alternatives mentioned in that article are much safer.
I wasn't considering other hypothesis mentioned in the article, as I've cited a casual article among many I found.
[...]you should use it with smaller amounts and also use it with people whom you trust more for now.
That's a good point. The issue is there
for the moment but probably it will be solved at some point.
I was asking in a practical sense, and of course about using it with whatever people, not only with those I trust as using money only with the people you just trust is quite a big limit.
For instance the exchange owners can be honest people for years and then just make an exit scam.
Why this technology is being promoted if it's not that secure at the moment? If people begin using it without being aware about the risks a big exit scam may greatly harm the image of BTC.
