I set my Metamask wallet up to be a chrome extension on my computer yesterday and someone hacked into it and stole all of my coins/tokens. The thing is, I'd just signed up for a program where you create nodes thru Strongblock and get paid passive income to host that node on the ethereum network, meaning that node is connected/Affiliated with your wallet. There is no reversing it and you have to have the node associated with a wallet. Now that the MM wallet has been hacked, what should I do?

?
Unfortunately, there is no way to recover your coins because transactions in the blockchain are generally considered irreversible if several confirmations have already taken place. Regarding the reasons hackers were able to break your wallet, it is not easy to identify the problem and how that exactly happened because you have given us too little information. For example, did you check if strongblock domain was genuine? It may be you have fallen victim to a phishing website that steals sensitive user information or makes you sign fake transactions. How do you store your Metamask seed phrase and password? Do you have them written up on a piece of paper or in Notepad, which is on the same device you installed the wallet?
I do understand that I cannot recover my coins. My biggest concern is the possible access to my Strongblock nodes. I bought 3 and they cost me a lot of money. I checked the strongblock site and it appeared to be the same one that all the youtube tutorials I watched on how to set the strongblock node up used. It is strongblock.com.
I have gone back to review one of youtube clips over and over and the difference I am noticing is that when I go to "strongblock.com" it takes me to the home page. When the youtuber is putting in strongblock.com, his home page says "strongblock.com/index.html". When I go to manually put in "strongblock.com/index.html", however, it takes me to the exact same page that strongblock.com is.
I could have gone wrong (and I'm not even sure) with the traderjoe site. I was using "traderjoexyz.com" and on the youtuber's video, he was on traderjoexyz.net. But then again, I dont even see why the domain holder would obtain the .net extension and not the .com extension.
When I downloaded the Metamask Chrome extension it asked me for my seed phrase. Since I'd never downloaded it on my computer before, I figured it was legitimate and that it was trying to authenticate my account. I really think this is where I messed up. Since the URL's of everything appeared to be legitimate I thought it was ok. I've seen one youtuber say it may ask for that during initial set up but that you should never have to enter that info again. My seed phrase was not stored online; I have them written down.
I'm devastated and not sure where to go from here. I can get over the lost eth and avax token they took out of my MM wallet. I'm just concerned about the hefty investment made in the 3 nodes. It would take me at least 4-5 months to recoup that based on the current price of the STRONG token and the amount of reward percentage they're paying out.
In the meanwhile, I have removed the Chrome extension. Is there a suggested method for claiming my rewards when it's time?? I'd planned to claim them once a month as to avoid recurring gas fees. Should I just install the MM when I'm ready to claim them, move the coins, and then off the wallet really fast? I at least want to get my investment back IF the hacker doesn't take that. I figure I have nothing else to loose..If I dont do it the coins are lost...If I try to move the coins really fast at least there's a slight chance of it going unnoticed by the hacker.
