Well keep in mind that Coinbase will not allow you to keep on both or all chains. Who knows about all the other exchanges.

If you care, you want to move all your coins to a wallet with a public key you control. That way you can make a choice about your coins on each chain. - sell or keep .

Go with https://electrum.org.

Coinbase or any other exchange is crazy not to support both chains, at least temporarily. It's a bit like stealing money.

Yep. I agree.

Although that point is clearly known. It is your fault if you don't have control over your coins.

My concern is that I've directed a lot of non-technical people to use Coinbase to purchase coins. Most of them don't have the technical skills to safely manage their own keys.

In that case, I trust Coinbase to not mess it up too badly. They stay in business by pleasing customers.

The new banks have much less stick and pull compared to traditional banks - something to keep in mind.

Kraken will mostly do the same right?

Not sure, I'd get my coins off their exchange though.

Okay great, thank you :)
