I am new to blockchain technology and exploring ways to build my own smart contracts or blockchain. I was initially exploring the PoS based Cardano platform but when I found that Smart Contracts in Cardano are still in develpment phase and yet to be released, I started looking for some other technology. Then I show Ethereum is a good platform to build Smart contracts but instead uses PoW with solidity which is easier to learn and many materials available online to learn(Plutus which is derivative of Haskell- which I found difficult to learn).
Now I am confused whether to use Ethereum or not to build my blockchain which has many scalability issues due to PoW that's why I was initially exploring Cardano. Is it worth it to concentrate my study on Ethereum?
It would be really helpful if someone could guide because I know very little about the field of Blockchain.
