Does it make more sense (timewise) to claim all the forks directly on coinomi? Except for BCD (IIRC), you can claim the rest directly with them; you move the private keys less times, make a single sweep, and can even dump everything for BTC at the same place.
Yes, that's faster. But I prefer to sign transactions offline, and BCH is the most valuable Forkcoin. Coinomi still doesn't let you split BCH-A though, and indeed BCD isn't supported.
What do you think about Bither wallet?
It supports more "exotic" Forkcoins than Coinomi, but it keeps crashing when I import a private key. So I gave up (and I trust Coinomi more). Bither was also very annoying to work with, part of the task had to be done in Bitpie instead of Bither.
Really sorry, but I'm not sure I understand the bolded part. Do you mean I need my private keys to transfer the coins to a new wallet? I plan on doing that with the BTC Core wallet, which would be using my private keys, obviously.
Then I can safely use my (now empty) old wallet to claim the coins, it I got it right.
Think of it this way: your wallet is a piggy bank, and any Forkcoin wallet you install gets full access to everything inside your piggy bank. If the wallet is malicious, it can steal everything! To prevent this, you take out as much as you can (AKA the Bitcoins) from your piggy bank before installing any Forkcoin wallet. And even then, you should be very careful what you install on your system as a compromised wallet would still get access to other data on your PC. That's why I only install Forkcoin wallets inside a
VM.
