I’m on eToro and it’s true what you say about never owning private keys. They keep saying that they’re going to introduce wallets, but it’s just happened. On the other hand, it is regulated by the FSA, unlike other rogue platforms, such as Plus500 and it’s the quickest way to open up a trade, without going through coinbase and then an exchange. I tend to by in blocks of 10, 100, or 1000, so that I don’t have to close all my position at once.
