Hi there anonszs! I just wondering how you bought bitcoin and litecoin without having a wallet. Anyway, based from my experience I use coinbase, I’m not connected or paid to endorse them but it seems fit to my need. The good feature of it is the ability to handle bitcoin, litecoin and even etherium, which is good thing because you can eve swap each other. The mobile app comes with it shows QR code for fast sending and receiving. Moreover, you can also buy and sell direct from the application. On the other hand, transaction cost could be pricey compare to other wallet. Hope it helps!
