I think that it is meaningless to start with amount less than 1 ETH, you probably won't be able to get something with smaller bank.
Indeed, I would rather hold that 1 ETH unless you have a deep understanding in trading. Also there is a high possibility of making a higher return if you are holding it.As of OP's question, you can start small for about $500 dollars to get some large, mid small caps of crypto in your portfolios, it will also cover your exchange fees when you are depositing money in an exchange.
