I just gave it a spin, and this is definitely useful. For newbies it's perfect because it sums up all the factors they don't understand at the moment into a simple rating. More experienced traders can use it as a reliable checker if they want to move their portfolio into more riskier field and re-think again if there are better moves.
I hope @clustr becomes mainstream as soon as possible, this will drastically decrease scams in crypto space and unleash true potential of the industry. Great work @clustr team.
