hello, who is official reseller of this bot ?
Everyone listed here:
https://gunthy.org/forum/index.php/topic,1241.0.html, as well as a few others that might not be listed yet. However, with the case of the latter we can't guarantee safety unless you explicitly verify the individual.
You should show us the PM sender. However, it looks like Captain Corporate (?). If it is truly him (and not an impostor account), then you are good to go.
Is it only on poloniex? I wanna use it on bittrex.
Poloniex, Bittrex, Cryptopia, Kraken. 0.1/0.09 (with discount) BTC per exchange.
Can this be used on laptop with operating 24/7?
Yes.
Will my laptop be damaged due to such a long hours operating?
No. However, if your battery can be removed and the laptop can operate via the cable only I would recommend that to preserve its quality.
Do I need VPS for operating this bot?
No, but I'd still recommend it.
How do I set it up?
Set up what? The VPS or the bot? There are a lot of guides on setting up a VPS online, and for the bot you can find guides on
https://gunthy.org/forum/index.php.
Is the bot got its trading strategy to trade with?
There comes a default setting and there are some shared strategies floating around the forums I believe.
Can I integrate my own trading strategy to the bot so it can trade my style?
Yes. You can twist and tweak parameters as much as you like.
Also is this gunbot only uses on Poloniex, what about bittrex?
Poloniex, Bittrex, Cryptopia, Kraken. 1 licence = 1 exchange.
