Don't use trust pilot for review.

To many a fake review, you can fake that. I believe around 0,5-1 BTC maybe a minimum 0,3 BTC depending on how many pairs you want to listing.

Sure, no worry.

Type exchange like this, they only want to list as many tokens as possible. Take the fee listing and then you know the next, your token will be dead volume + sometimes only full of fake transaction by bot exchange.
