I had invested in cardano as it is energy efficient and nature friendly. It is secure and I also made pretty much profit by investing in it.
Caradano has a unique approach and so has a very well future scope.
I also think that cardano is very safe to invest in because its performance shows stability and certainty
it was announced that Cardano had finally achieved 100% decentralisation.
What this now means is that block production is now in the hands of the network’s stake pool operators.
Also Cardano's price predictions for 2022 look good
There are also constant updates in cardona which makes it event more secure and suitable.
Cardano’s price had increased by 720% by the end of February 2021 since the start of the year, reaching an all-time high.
