Active investing meaning that you will do your own trades. You can choose to trade all sorts of things, and your are responsible for buying and selling the asset in order to make a profit. An asset can be various things such as stocks, forexes (currencies), commodities (such as gold and oil) or cryptos. I only trade stocks and ETFs and if you want to read more about my choices head to my blog.
If you want to do your own trading. Make sure you read my guide to eToro, where you can trade all of the assets mentioned above. However, you cannot trade all cryptos at eToro, so if you are looking for cryptos only, you can read my guide to Coinbase.
