I definitely wouldn't recommend Atomicwallet. As mentioned above, the wallet is supposed to be non-custodial, and yet many users have recently got their funds stolen[1] and what's crazy about this whole thing is that even now, after more than a month from the incident, the company still claim that they don't know what caused this which doesn't make much sense when they recently pushed a "mandatory security update"[2]
