Blockchain Wallet is one of the most reliable wallets out there, it supports in addition to bitcoin, currencies like Ripple, Eos, Bitcoin Cash, Stellar. Your security is a fundamental point for such success, in my point of view it is one of the most secure web portfolios in existence, the user needs to verify his login via email every time he logs in, his login can be done by email or with user id. In the blockchain wallet a user can have several wallets created, but only one of them can be verified to level 2, that is, have their data verified in order to be able to take advantage of their resources. An option that I have used for some time to store my biticoin and my stellars.
