Found a new universal solution for crypto as a newcomer. I can store and buy safely cause of the Bitgo provider. Funds are held at an accredited service. One of the largest and most reliable cryptocurrency custody services with funds insurance. All procedures are carried out within the framework of the AMLCTF policy. 3 step verification is not even a problem here.
The personal wallet interface is super accessible. In Connectee you can see all currencies with balances, and transfer history immediately in the system.   
A separate mention should be made of the customer-oriented service. You can get answers to even the most complicated questions from a support team in a couple of clicks, without unnecessary actions and in a couple of minutes.
One more. Visa plastic and virtual cards will be issued soon. So you can buy more than 14 cryptocurrencies with card payment and pay with crypto everywhere using a debit card.
