smart phone is not good device to mine & it will not be a wise decision. better you can try cpu mining.

You can open wallet on Blockchain.info or Coinpayments.net and buy some btc from here.
Also you can try Changelly.com for exchange.

if not necessary please hold it for a while, its increasing day by day. after a certain period you can do a lot with a small amount of bitcoin. 

That's a very good news, Japan's airlines is accepting bitcoin. More people are starting to know about Bitcoin. Other countries and a lot of companies are now adopting bitcoin, so they can also get the advantage of bitcoin and it will be great for bitcoin because it will get more popularity.

BAT's policy is very interesting. COIN sold out in minutes,wish i had some in it. Its on ETH based. They briefed detail in their whitepaper.
The guy behind BAT is Brendan Eich, the creator of JavaScript and the co-founder of Mozilla and Firefox, with a solid team – funded by Founders Fund, Foundation Capital, Propel Venture Partners, Pantera Capital, DCG, Danhua Capital, Huiyin Blockchain Venture among others.
To be honest ...woow.

from when i started to using btc i am using coinbase as wallet. its quite good but not perfect. i am not familiar with ledger nano, seems hardware wallet to me.

I think bitcoin is better investment than the gold now a days.
But gold is trusted from the beginning.
So,we have to choose investments wisely and productively.
