In our opinion, the Exodus wallet seems to be the most reliable at the moment. It offers a wide choice of cryptoassets and a good level of security. You can download it directly via this link. Here, you will find a video tutorial which explains how Exodus operates on PC/Mac.
It is EXTREMELY IMPORTANT to back up your Exodus wallet (7:40 in the video). The backup of the wallet is represented in the form of a list of words to copy onto paper. For more information on the backup sentence, please see the question 'How do I back up my wallet?'.
Note: The implementation of the backup is only possible from the point when you carried out your first transaction to Exodus.
