If you're just looking to do some trading with high visibility into managing costs in both traditional investments as well as crypto, eToro is a great option. If you want to do more than just have exposure to crypto markets, like use smart contracts or use other computing features of a cryptocurrency, you might want to use a platform more geared to that.
I have not used any product as comprehensive as eToro or that is comparable to eToro. I have used and continue to use other online trading platforms, but these services are mainly geared towards facilitating trading only. Unlike eToro, they do not offer any decent degree of trader/investor education, or value-added services, such as access to the WSJ and Financial Times or a dedicated account manager
