Bitbns is a really good exchange to trade some cryptocurrencies like Ripple. Just transfer them later into a better wallet.
Trade in Bitbns and transfer your coins to Coindelta. This is what I generally do. Works super fine.
I don't know about Indx, but Bitbns is a pretty cool exchange. Got my KYC verification done within a day. The exchange rates are almost equal as all other major exchanges. Not so sure about its wallet though. I bought some Ripples from Bitbns and transferred them to my Koinex account.
I get what you're doing but don't you think it will look a bit convincing it you'll slightly change the names of your newly-made account for promoting or in simple word spamming.
You're right. Not only all three accounts were registered at almost same time, they also posted in almost same topics (checked their post history).
And they're shilling the same exchange on this thread. I advice to ignore their advice and stick to our own judgment.
