I can confirm that Goldario is very likely a scam coin. They have a huge telegram following (50k+ members). Posted some questions about Goldario and was instantly banned from posting further on that channel. I would stay far away from this altcoin.
Having 50,000 members means little nowadays as those are mostly bots that you can buy in bulk for pennies and rest consists of airdrop and bounty hunters, with very few genuine users that are actually investing in this (I would say less then 1 %). Out of curiosity I just checked their telegram group and as expected it is mostly dead, with occasional questions like "when bounty tokens distribution" and similar irrelevant stuff. I do hope that's the sign that their scheme is not working well and people are not falling for it.
