I'll start with a short version
First, make a backup of your wallet.dat. Then, make another backup on another device (USB stick), and another backup!
Then, get a secure computer. If you're looking at several Bitcoins, it may very well be worth to install a Linux distribution. There's no rush, learn before you do things! Or buy a new laptop just to be sure it's free from malware, it's a small investment if you're holding several Bitcoins.
That being said, I can do everything you're asking for, but there's this:
General note: never give your private key or word seed phrase to anybody! If you're not the sole owner of your private keys, you're not the owner at all!
If you want me to claim your forked coins for you, you're going to have to give me your private key(s). Now, read the sentence above this again. Are you confused yet? That was intentional to make you realize what you're about to do!
You should NOT risk your Bitcoins. Period! Your Bitcoin is more than 98% of the value of your wallet.
After you've securely moved your Bitcoin,
I can extract your Forkcoins for you:
I can't claim all Forks, only the ones that are worth it. I can extract these Forks:
BCH: $480
BSV: $180
BCH-A: $14
BTG: $25
BCD: $9
Current rates are a tad higher than quoted above.
several-dozen wallets
If you literally have several dozens of wallets, you can do them one at a time.
Thanks @all - like I said - I wanted to skip having to waste days learning all the new ropes (software, sensible fees, new wallet formats - for every damned fork)...
What's a few days on 9 years?
You don't need "all" Forks, most are pretty worthless so you can just skip them.
I don't think it's
TryNinja's site. And I've seen it give incorrect results on several occasions. I use it, but don't assume it's correct.
You should ignore all PMs you receive, offering to "
help" you. People have been scammed that way.
