How to start Bitcoin-qt with Bitcoin Cash? First of all I do not trust online wallets so I download full blockchain with Bitcoin-ABC. Unfortunaly bitcoin-abc does not contain bitcoin-qt binary. So my question is it possible to start original Bitcoin-QT with bitcoin-abc? 

if this is not possible, what is the other way to use my wallet under bitcoin-abc?

Thanks!
Bitcoin ABC 0.16.1 binaries for linux have a QT GUI:
https://download.bitcoinabc.org/0.16.1/linux/ - I have not checked the other platforms, but I assume they do too.

They kept the same binary names (bitcoin-qt, bitcoind, etc) when they forked Bitcoin Core, which is a bit confusing because it is a seperate network with its own consensus rules.

The standard bitcoin-qt (Bitcoin Core) only works for bitcoin, not bcash.
