We are in bubble mode right now and most of coins are over-pumped.
In your opinion, which crypto-asset on the market today is less overpriced compared to real long-term opportunity? Is there any project with strong technical development and low level of PR / promotion?
think xmr, because it was overshadowed by the rise of the value of other coins, and he remained in an extremely modified form.
XMR isn't really overshadowed at all. It actually had a pump of its own very recently and it's still in the process of correcting it.
