3. I see now that they have Bitcoin Gold app, can i claim them same way as Bitcoin Cash?


Yes - but: there are is only one exchange at this time where you can move the funds in case you want to sell it. It is a small exchange and I don't know how reliable it is, so you may be better off waiting until more exchanges are able to receive funds. All other exchanges which has bitcoin gold in it, haven't yet wallets to receive bitcoin gold from the outside.

Aside from HitBTC, there is also "changelly.com"... nice little insta-sell if you don't mind the rates.

Question: I have several ERC20 tokens, currently hold in Coinomi mobile wallet.
I want to transfer them to Ledger - is there a way to scan/replicate/teleport/sweep my funds from Coinomi to Ledger OTHER than simply send tokens?
I'm asking, cause transfer fees for ERC20 are awfully expensive comparing to other coins...

PS. is it safe to bond Ledger with MyEtherWallet? I'm not a big fan of online wallets...

You can, but not "safely"...

That is to say, you could always try restoring your Coinomi seed into the Ledger... which should theoretically clone the Coinomi wallet. But that would totally defeat the entire purpose of having the Ledger (ie. your seed/private keys have NEVER been "outside" the Ledger).

The only truly safe way is to simply send the tokens to the wallet(s) on your Ledger (that was initialised with a seed in a "safe" manner, ie. inbuilt initialisation, or restored using a seed generated offline with dice etc).

Ledger and MEW is a safe combination. The private keys/seed cannot be accessed from outside the Ledger. The worse that could happen is that MEW could leak your "public" keys and/or addresses and compromise your privacy.

Yeah, I didn't want to restore my Coinomi wallet to Ledger, but rather "sweep paper wallet" for only one coin.
But I got it, the best way in terms of security is to transfer them. Thanks.

But is leaking public keys a danger to my funds? I mean, by having access to my public keys is anyone able to "touch" my coins or tokens?

Thank you very much for help!

As HCP already mentioned, it is only a possible compromise to your privacy. If someone knows your public key/address, they can see how much you have. That's it. They can't touch it.

"Sweeping" means to send all funds from one wallet (e.g. paper wallet) to another wallet (the one you are speewing it into).
Most wallet softwares let you "sweep" your funds. But what basically happens is they import the private keys, sign and broadcast a transaction with all funds being sent
to an address generated by the wallet software itself.

No. Just your privacy is 'at risk'. Security-wise everything is fine.

Thank you all! Sorry for bothering, but this is all still new stuff to me. I've started trading/buying/learning like 2 weeks ago, so please forgive me if I will ask stupid questions (stupid for old users), as my time for learning is strictly limited (2 little kids, just to say).

Anyway, these answers fully satisfies me, as I really have no issues with revealing, how much I have (not much Wink for now, so...).
If the security is not compromised here, I'm all good.

And I was thinking, that "sweeping" is some magical Cheesy way to teleport my funds.
Apparently, that is not the case Wink

Yeah... I'm not sure where the term "sweeping" originated, but I can see that it can be a bit misleading for new users. I know, when I first started out, that I too thought that "sweeping" was some special action for moving coins from one wallet to another.

After an afternoon of digging, I discovered that it was simply a "short cut" method of "importing private keys->create transaction->send transaction". Rather, you just enter a bunch of private keys and the wallet will go find all the coins and send them somewhere... usually to itself, but some wallets allow you to sweep to arbitrary addresses.

So, I guess the important distinction between sweeping and importing is that sweeping creates a transaction using your private keys and sends coins to a new address but the keys are then forgotten, whereas importing actually imports the private keys (or seed) into your wallet and acquires the coins that way.

Sweeping is generally deemed safer, as the "exposed" private keys are generally "forgotten" and not used again, minimising the chance of coin loss via your keys having been compromised... whereas, with an import, keyloggers/memory-clipboard scanners/screengrabbers etc have the opportunity to work their mischief if your coins are still sitting on the same keys you've just typed or copy/pasted etc.
