XBY was way overhyped.
I don't know if its a total scam but it got pumped, and it gained a cult following overnight.
People were acting like it was the next revolution in crypto, which is a pretty big claim.

Remember its very easy to manipulate the price of a new coin when it has a small market cap and is only on a couple small exchanges.

Maybe XBY end up being good but its got a small team working on it and for me that means it will be a while before I think a coin is worth more than a few million market cap.
(Unless I have some inside information or the developers have a proven track record on other projects.)
