I haven't seen any wallet that would support top-10 cryptos at the same time, especially mobile versions. My Ledger wallet supported 5 cryptos simultaneously, Coinomi - about 7 or 8 (no XRP, Stellar and EOS). Bitcoin Core - for BTC only, MEW - for ether and ERC-20 tokens, no other altcoins.
Atomic wallet supports all top-10 coins, including XRP, Stellar, EOS. Bitpie also supports a large number of coins and especially a lot of tokens on ETH, TRX, EOS.
Agree with you. I used Atomic wallet once but found it inconvenient and user-unfirendly, especially in the part on copying addresses of the wallets. It's also loading too slow when scrolling down to observe other wallets available. Maybe it's due to my PC poor capacity. Haven't you face the same issues?
