As per my understanding Cardano got an opportunity and they lost it. Staking started recently, but you cannot expect it to perform similar to Ethereum staking. Although the results are better than Ethereum and when compared to the price it is more comfortable for anyone to purchase & stake it.
My opinion is that except Bitcoin (if you bought before 2011) you wouldn't be able to create financial freedom. That being said, the price point of Bitcoin at the moment is encouraging. I know that Bitcoin is too costly, investing in small amount can lead you to financial freedom. Whereas investing in altcoin is beneficial if you know what to do!
If you can DYOR on that project before investing.
Not everyone can afford 1 Bitcoin, you need to invest in it every month, and sometime in the future, you would accumulate 1 Bitcoin. Through staking, you will be able to do it fast using a cryptocurrency like Cardano. 1 ETH is out of reach for a common man, you can start staking with a small amount, but the desired return won't be high. If you are completely focused on the staking process of ADA at its price point, you can purchase more than 1 ADA and start staking with good returns.
