You won't get BTC, only LISK and only after the launch of Lisk. Right now there is no network we could use to transfer the LISK.

Yes. Bonus is taken from the time of transaction as others already said.

They had a different vision on future development. Lisk is a fork of Crypti, so at present time there is not much difference.
The most prominent change is block rewards for forgers which provides incentive for people to delegate and secure the network.
As time passes they will begin to drift apart and the technical advantages should become clearer.
Exactly. Olivier and I are already working on the next features. It will take a few weeks to really see a big differences between Lisk and Crypti. But this time will definitely come sooner than later.
