better to use the pc only if doing mining to get results and more convenient. When using a mobile phone then it is a pity because it was too heavy to use the application and don't get too comfortable, too.

Free staking, the first wallet which support ledger! You will be able to stake in your ledger!

I will recommend you go for a promising project like Neo. No one can predict how far this promising coin is gonna go looking at the potentials the coin posses. Also the current market dip has even offered a chance of having some investment in ETH; another promising project if you really posses the financial wherewithal.

My favorite is Jibrel Network because of its cleae vision and new-edge tech. Most of the ICOs are ambiguous in describing their vision and talk bla-bla about future. But Jibrel Network is not like them and built a great wallet.
