Advice :- If you do not know what you are investing just keep away from it.
Instead of cardano just look at ARB, SUI, BNB
No need to try over serious because of want details about cardano, which is good or bad investment issue. Away so cardano still have good invest in my mind because they have many investors community and there have many service where investors can makes some profits. Just a old project sometime believes us even you can buy dip, if the price of cardano gonna to down.
