Any fork that doesn't support SegWit will make claiming fork coins difficult. Also, there is currently no method for signing messages from a SegWit address ("3" or "bc1")... so participating in some ICO's and/or AirDrops could be problematic if you have a SegWit wallet.

You can sign a message from a bech32/base32 "bc1" address but only someone using Electrum will be able to verify it until other wallets and Core catches up.

Like I said... ONLY if your wallet is supporting SegWit addresses properly... You might like to read: https://bitcoincore.org/en/segwit_wallet_dev/

The "native" SegWit address specifications are NOT finalised. But if your SegWit address starts with a "3", you shouldn't have any issues... the network can't tell it apart from legacy "3" addresses used for MultiSig etc... at least, not until you attempt to spend.

But we can always send Bitcoins from a legend address to a Segwit address without problems?

1) OK. But Segwit with Electrum and Trezor should be compatible with other Segwit Wallets?

Trezor is using "3"-type (aka P2SH-P2WKH) SegWit addresses... I'm not sure if you can actually specify if Electrum should import the SegWit or Legacy wallet from a hardware wallet like Trezor or Ledger... I think it will just import the "legacy" wallet "xpub" from the device.

2) What happens when I try to send FROM "other wallets ("3" type)" to Electrum SegWit ("bc1" type).
Is there an error? Or would I lose my coins? What would happen?

If they support bech32 addresses... it should send just fine... if they don't they will more than likely give a "invalid address" error.

3) Is there a reason never to use Segwit and stick with the legend addresses? Can this be any advantage?

Also, it will mean you can only migrate to a SegWit supporting wallet in the future...

Most other wallets and services will most likely NOT be able to send to an Electrum SegWit wallet... Electrum uses "bech32" address that start "bc1"... As far as I'm aware, Electrum is the ONLY wallet that currently supports this address type. You should be able to send FROM your Electrum SegWit wallet to other wallets just fine.

Other wallets use the "3" type addresses for their SegWit implementations, which pretty much ALL wallets should be able to send to.

Some time ago Electrum has implemented segwit. Before I try it out I want to ask:

Is it in the meantime secure to send bitcoins to the new segwit addresses with electrum?
Or are there any problems?

Thank you.
