1.Is this the end of bitcoin?
Nope, it is just another start and another big rise for bitcoin.
2.Would most of the users switch to BCH ?
How will they if the price are now going down? It is just another scheme where the people that backing these altcoin to attract many bitcoin users, but from what is happening now, I guess they have failed.
3. Is BTC still going to recover as time goes?
Bitcoin always recover when it dumps. When the price goes down, some investors and users take this as an advantage and buy some bitcoin to hold for another pump and another profit.
No doubt btc will keep still, btc is able to withstand the dumped since some whales or group targeting to buy more, bch can be a good way to xo some transactions for fees but it still btc we tend to use for long term.
