I can answer to some of your questions because I asked the same on their telegram channel.
1) You can select the language on the top right, however there are some pages that are present only in Italian. They are completing the translation. Ah, and the main developers are italians.
Only top right window i am getting, comes from browsers that have automatic translation system. So that would implicate that they are lying about completing the translation when they haven't done it in the first place.
2) No, and this done on purpose to decrease the risk to incurr in frauds with small exchanges
If they just would have said no, this wouldn't be a red signal. Now it sounds like they are giving excuses. There are older, more legit and more time tested exchanges then binance. And implicating that they are smaller and a scam risk, is a comment from someone who doesn't know much about this space.
3) No, for the moment I see only btc-usdt. Others will come, but there is no ETA
Then what does this mean:
-cut-
Pick a bot, allocate your amount, select your currencies, and you’re off to the races!
-cut-
4) No
This option be only reason why i would be interested, but they already blew it with their answers.
