Which perks and features should one look for in a wallet?
Thanks in advance
What is your purpose first ? If you just want to trading your coin in the market, using exchange wallet is enough.
But if you want to hold coin in your wallet, i think you must have a secure wallet like hardwallet.
Or at least using desktop wallet to securely storing your coin for long period.
Online wallet like blockchain and myetherwallet are fine too but not for a long time holder, if OP want to use wallet for hold coins for a long time like some months or years, then it will be better if OP buy a hardware wallet like Trezor or use desktop wallet like Electrum.
