You can do so many things with your bitcoin. First you can trade your bitcoin with some altcoins. There are so many good ICO projects. You can invest that bitcoin to ICO project. If you can't do anything with bitcoin just hold it.

I'm using Huobi. I have good experience with Huobi. I didn't got any problem. It's good exchange. Easy to use and you can trade with your mobile app.

You can participate bounties and airdrop campaign. Bounties mean before start any ICO projects they do marketing programme. You have to do small weekly tasks like Twitter, Facebook sharing, Bitcointalk signature wearing etc. They pay you vis their own tokens on ICO project. You can get the payment after the ICO. When that tokens hit on any exchange you can exchange to bitcoin. Airdrop campaigns are some ICO projects giving free tokens. You have to do one time simple task like retweet, join their telegram group etc. They will pay you free tokens for it. When that tokens hit on exchange you can exchange to bitcoin. Now you can understand how you can earn bitcoin without investing.

First go their website and take a idea about what is the project. Read their whitepaper and check out about team members. Check how much is bounty allocation and how they manage campaign.

Litecoin is one of best coin in crypto market. So many sites. ICO projects are accepting Litecoin. Because Litecoin transaction fees are pretty low and transaction speed is very good. I think Litecoin has a good future in crypto market.

Do you think mobile mining is useful? I don't think so because it's wasting your data, battery and time. Mobile mining apps are not good for your phone.

No one knows. Some people says Ethereum will be beat Bitcoin. I don't think so any currency can beat Bitcoin. Beacuse all trading sites based with Bitcoin as a main currency. Just look at coinmarketcap, Bitcoin marketcap is more than 2x in coinmarketcap. But we have a risk something will happen in future.

You don't need any merit to be a Jr. Member. If you are a Jr. Member first you have to go Profile>Forum Profile Information>Signature and copy paste signature code to empty box.

You can go here below link for bounties section

This is good site for find latest bounties and they have rating section too. It will be helps to find good bounties.

Yes you can, But it's wasting your data, Battery power and it's not good for phone. Then don't do it. If you wanna mine buy a gaming PC.

Bitcoin price is so high right now. If you wanna earn bitcoin with faucets it's useless and time wasting. Buy some bitcoin and hold it or trade with altcoins.

What do you need to know? About trade tokens or bounties? Okay, If you need to join bounties first you need those things

Twitter account with real followers (Minimum 200 followers)

You can find lot of bounties in this thread
https://bitcointalk.org/index.php?board=238.0

You can understand about weekly tasks when you read the one of bounty thread. If you need to join a one you have to fill a google form.

First of all you have to make ERC20 tokens supported wallet (Myetherwallet, Metamask) and NEP5 tokens supported wallet (Neotracker) for get bounty payments. Most ICO projects are based with ethererum that means ERC20. You can give that wallet address to your bounty registration form.

When after the ICO if you work with bounty project well you can receive payment for your wallet. After that you can trade that tokens when will them hit exchanges. You can find that tokens hit what exchange from their Telegram, Twitter or any social media. If you find that you can exchange that tokens to any currency.

I didn't hear main exchanges are restricted in Hawaii. You can use Bittrex, Poloniex, Binance, Hitbtc and more.
