I need help

Hi, I wanna learn about cryptocurrencies and I’m interested in Ethereum as everyone has been telling me that it will go up in the next couple of years.

How to start? And is Binance a good platform? I actually did buy ETH a couple of days ago I got 0.0142922 and on the 11th of this month ETH went down a lot. Do you think I should buy more today ? Because I saw the price started getting higher again.

And lastly is ETH good for daily trading ? I need help from someone who knows about these things I’m a beginner. Thank you
