Can someone help me with wallet for linux? I installed version 1.3.6cg to Lubuntu 17.10 and started run.sh. When I enter the wallet in browser I  always see "Downloading blockchain" and several days passed. How can I see the progress and know if it is not stuck?

Is there a bot, in which you just enter the coin, quantity and press buy to buy all lowest orders available and when you press sell - it sells to highest orders available? With less automation that is. So that you control when to buy and when to sell.

Everything went OK. My bitcoins appeared. I am happy. It seems Bitcoin Core and Bitcoin ABC have completely compatible wallet.dat

I hope you are right. Thank you. I will sleep a little better tonight ).

Yes, I did and quite some. Why I think something is wrong is because Bitcoin Core showed me 0 balance when started with that command.

So I have problem with BTC, not BCC

I will try to explain again step by step.

Installed Bitcoin ABC, pointed to F:\BitcoinCash, it started and synchronized, there is big database and wallet.dat
Installed Bitcoin Core, pointed to F:\Bitcoin, it started and synchronized, there is big database and wallet.dat
Then I made a shortcut, "C:\Program Files\Bitcoin\bitcoin-qt.exe" -datadir=f:\BitCoinCash\, which starts Bitcoin Core and makes it use BitcoinCash folder
I put money to Bitcoin Core launched like that, everything is ok
There is transaction problem, I do this:
"C:\Program Files\Bitcoin\bitcoin-qt.exe" -datadir=f:\BitCoinCash\ -zapwallettxes
Bitcoin Core starts, but shows 0 bitcoins (although it shouldn't)
Then I close it. Copy F:\BitcoinCash\wallet.dat to F:\Bitcoin\, correct the shorcut and start it:
"C:\Program Files\Bitcoin\bitcoin-qt.exe" -datadir=f:\BitCoinCash\
And right now I am waiting for sync and praying

The only thing I have is wallet.dat file, initially generated by Bitcoin Cash, then used by Bitcoin Core and then somehow modified by me supplying -zapwallettxes command to BitCoin Core.

Something really terrible happened. I installed Bitcoin Core and Bitcoin ABC (Bitcoin Cash) and pointed them to different folders. But then by accident I pointed the Bitcoin shortcuts to Bitcoin Cash folder. I didn't even know and started using it because it didn't even warn me. Then there was a transaction problem which I tried to solve with -zapwallettxes command. Bitcoin Core started and showed 0 bitcoins. I panicked and closed it and then noticed the folders error. All this time Bitcoin Core has been using Bitcoin Cash folder, including the wallet.dat. Now I put the wallet.dat in Bitcoin folder and started Bitcoin Core and am waiting for synchronization now to see if the wallet it ok. But there is high probability that it will show me 0 bitcoins again. Please help! Do you think wallet.dat could get corrupt and if yes is there any way to fix it?
