I am one of the people who is very careful with the coins that I will choose to invest there,
one of the indicators that I see is the github account on the project,
and one of them is Cardano, I really trust the cardano because the dev cardano is very active, this can be seen on the official github cardano link, almost every hour there is always an update on the github cardano.
and this proves that the dev cardano is active.
