I use electrum to hold bitcoins and imtoken for ethereum and ERC-20 tokens.
You can go with that, or choose one that suits your strategy better.
I wanted to try where you buy at low price and resell at higher value.
Everyone wants to do this. It's not as easy to do. The safest path would be hodling, and your safest bet would be bitcoins. You could also sell at a higher value and buy later when it drops. There are many trading strategies and you'd need to learn about them, it's good you are into stocks that will help you get settled in quickly into cryptocurrency trading
