if I have a capital of $ 100 then I will buy bitcoin so that I can sell and buy directly to get a quick profit. because Bitcoin movement in the exchange market is faster than Ethereum and Bitcoin Volume is bigger than Ethereum. so I think Bitcoin is better than Ethereum.
In terms of market liquidity, yes bitcoin is the best. A comparison is no longer needed for these two, everyone will agree that bitcoin is better and not just better but best in all of the crypto markets.
Ethereum has its quality and it's also preferred by many investors because it's 2nd to the list.
