Well, from what I understand, when you get paid as part of a bounty program, it's basically like you are part of the ICO, except they are giving you the coins/tokens in exchange for the work you did promoting their ICO.

Unless being paid bounty is technically different than ICO, which I would be glad, because I would like to start earning some bounties.

I just realized that most of the bounty reward tokens would be considered to be ICOs. Does that mean all bounty campaigns are not willing to let US residents participate?

Which token are you talking about specifically?

I don't believe there are any rules against participating in multiple twitter bounty campaigns simultaneously, unless like you said, the rules specifically forbid it.

I believe many members are currently promoting multiple campaigns without any trouble. 

I too am very interested in subscribing to Palm Beach Confidential based on their past performance in the crypto-space.

In terms of stability Litecoin is a relatively safe investment — as far as crypto goes, that is. Very quick transaction times and low fees and widely traded on exchanges.

Never gets the media exposure of Bitcoin but is one of the few truly legitimate coins.

If you have a reasonable amount of money invested in crypto I would invest in a hardware wallet like a Trezor or Ledger Nano. If you want to be really, really safe you can put your crypto in cold storage, but if you are moving your funds around regularly this would not be a very convenient option.

Yes there is. Next time, use a higher transaction fee. It the transaction fee is too low, which in your case it seems like it is, no one will want to mine (process) that transaction so it may be stuck indefinitely.

If you send with proper transaction fees, which as of right now around averaging around $25, the transaction should be confirmed in about 30min to an hour.

Pretty sure its because the transaction didn't use enough gas (fees). The ETH should still be in your wallet, shouldn't have gone anywhere as the transaction failed.

Cointracking.info is not technically a mobile app but you can view it on your phone and it updates values for all cryptos daily. Very advanced tool for crypto portfolio tracking and analytics.

If you want to buy other cryptos, which many people refer to collectively as "altcoins," you will need either BTC or ETH to purchase them with. Most altcoins trade against BTC and ETH. So usually people will buy BTC with cash in their local currency, and then send BTC into an exchange to trade for altcoins.

Some altcoins can be bought directly with fiat (regular money) on some exchanges, but you usually are required to go through a lengthy verification process with the exchange.

In my personal experience Coinbase has been very easy to use, it's one of the easiest way to purchase BTC/ETH/LTC, only thing though is that you will have to wait over a week until you actually have the crypto in your wallet. You can also do an instant buy with a debit/credit card for smaller amounts of crypto that are available to use instantly.

Unfortunately you'll have to go back and edit them manually. All the airdrops are run by their respective ICOs, there is no "master" Google Docs spreadsheet with all the airdrops you've registered for — unless you've been keeping your own. I just started and am already losing track of what I registered for as well, so I will need to keep up my records also.

It can be a bit overwhelming at first. I assume that you are interested in investing/purchasing bitcoin? Or were you just wanting to learn more about the underlying technology?
