Matbi was recommended to me as a reliable service for cryptocurrency. They have both a wallet and an exchange. You can buy and store, waiting for growth, or sell if you have concerns about a drop in the rate. I haven't encountered such a universal approach anywhere else, at least among well-known and safe options. Friends mentioned that they couldn't open a wallet due to a complicated registration process. That is indeed true. But it's better to go through all the difficulties once, confirming your rights to the account and identity, than to face withdrawal blocks or frozen accounts later.
