Its not technical IMHO. Some common description and basic notes.
It does not clarify what exchanges support what and ive read that Bitfinex going to support fork.
No mentioning about lending or investing in casino. Last time crypto-games split bitcoin fair and fast.
It may be not that technical but it does tell you the right thing to do. Like what you said, you are not sure what Bitfinex supports, or if Bitcoin casinos will split your coins for you. The guide tells you how to put all your coins in a wallet that allows you to control your private key, and all the reasons why.
Its more of "Hide yo women, vikings are coming"
You do not believe in doing the right thing to keep your coins safe?
Put the coins in a wallet which you own the private keys for, that is the minimum anyone should do or advice.
rather than blindly trust exchanges to do the right thing.
Exchanges have shown they have no inclination to give users the forked coins.
Why should they really...
Ofcourse some of them may slide with the gold or 2x developers and list the fork coins, if I am not wrong bitfinex is already speculating on the prices
but they have no obligation to do so.
Many fiat exchanges simply will not accept the new coins because that would involve significant restructuring of their existing systems, cold storage wallets etc.
