It is true that for a coin to be considered as a currency, stability of the value is a must. Bitcoin value is currently unstable and sometimes extremely volatile, but bitcoin is just on its infant state. Wait till people starts to adopt and use bitcoin on daily basis. A time might come where we might a stable price with less fluctuation.

Before you start investing, do some research. Analyze the coins you are going to invest in. Since you are a newbie, starting with small amount is actually a sensible thing to do. But you don't want to be losing those coins and get demotivated. So better learn before you start.
$100 won't get you much profit. Try investing those on some casinos, while you save more coins to invest?

Won't be talking about everything you said. Just few things that got my attention.
You send bitcoin from one wallet to another wallet which is situated on a different part of world, it just takes less than few seconds for the receiver to receive the coins. With just few clicks, nothing could be more simpler. It's only the confirmation that takes time currently which can be avoided by paying higher fee. A solution is about to come soon!

No cap = high supply = less value.

Gold is used as a form of storing wealth. Bitcoin is also used by some people to store their wealth, so it can be equivalent to digital gold.

It is never too late. If you believe in bitcoin, you should invest and hold. Do not let your emotions get to you. Seeing all those price fluctuation might tempt you to sell your coins, but do not.
But if you want to stay totally risk free, wait till august 1st and few more weeks. We do not know yet what is going to happen. So better be safe than sorry.

Did a little bit of googling, you can find you answer here https://99bitcoins.com/bitcoin-arbitrage/
They explained it well!
Read "Barriers to Bitcoin Arbitrage" if you don't want to read the whole article. They sum up everything really good.

1 Poloniex has been here for a long time. Most of them i guess are traders looking to make profit and invest on other alt coins.
2 I use both bittrex and poloniex, but i prefer poloniex over bittrex. Polo has a better looking interface. Use it mainly for trading.
3 A good customer support.
4 Currently there are lots of exchanges, so competition is high. If you think you can offer something better and unique you could try. Else better off investing on something else.
5 Depends on what coin you are mining.
6 You forgot to consider the "FEE" you will be spending which will eat up your profit. And also speed matters. You might end up making loss. A very risky thing to try. You might also not be able to sell at the price shown, since no sell order might be open.

So doubling your bet, won't it make your gambling more riskier? I know it helps to recover your initial losing bet, but what if you lose your next bet too? You will double it and if you lose again you will have to double it (assuming 50-50% chance). So more riskier than arbitrary betting in my opinion!

It was a low amount bet(and probably from faucet), which is why he was able to bet with it without any fear. I don't think anyone would be willing to risk a high bet with just  a 9.90% chance of winning.
Nice hit though.

Doge coin was (is?) actually a joke coin where the developers made it just for fun. The coin ended up surviving till today thanks to the active community and the developers.
You answered your own question.

You can use the faucet to get some playmoney and gamble with it.

Like we said you can gamble with it and convert your playmoney to bitcoins or other altcoins using the exchange service offered by the casino.
Why don't you try it out? 

Internet is actually the best source to learn! Google will help you find topics. You can watch videos on youtube to learn. There are some youtubers whose channels mainly focus on the crypto market and trading. Maybe subscribe to them?
Another good way to learn is by asking questions. The more you ask the more you learn. Look for threads which discusses about trading and try interacting with them. Ask them questions and they will answer.

Do your own research. Look for coins with active community and good developers. Search for coins which has higher potential and is reliable. Keep an eye on ANN threads, read what users have to say about the coins (Some might spread FUD, so be careful!). Study the market. You might want to spread your investment on different alt coins, its less riskier.

In my opinion it is actually worth getting into, especially now. If you like to write and read it is a must for you. You might get frustrated at first first, won't be getting much earnings. But keep doing quality posts and people will start following you. More followers = more potential of making money. And if a whale likes your post, consider yourself lucky

Lots of ways to spend your coins.
Bitcoin itself is a form of investment, but you can maximize your profit by investing on other altcoins. But make sure you understand what you are doing. Its a risky business, but the returns you might get is heavenly.
Have you tried gambling with your coins? Its a risk too, but fun (NOT fun if you start losing your coins  ). You can try CRYPTO-GAMES.NET for gambling. They have been here for a while, and long time users get rewarded. Remember, always risk what you can afford to lose.

You can shop online using bitcoins. There are plenty of sites which accepts bitcoin as payments. Few users already linked you to those sites, so i won't be doing it again. Some sites may not accept bitcoin, but if those sites have gift cards that can be used, you will find some third party sites selling those cards for bitcoins. You might also find users selling those cards on this forum. But be aware that those cards might be stolen, so never buy cards from untrusted user.  If you still don't find those cards, there are  ways around. You can get a virtual credit card (VCC) and load your card using bitcoin. It will work on any site which accepts VISA/MASTERCARD. You can try advcash for getting your VCC. You have full control over your card, and you can check your spending history.

Try to see if you can somehow trace and track where the coins are going. Maybe try getting the IP address from poloniex (though the thief can still mask his IP)? One information might lead you to another which in turn might help you catch the thief.
You can file a report, but i don't think the authorities might be able to do/help much. But provide them with as much information as you can.

It's fun to play (but frustrating if you keep on losing   ) and helps pass your time during leisure hours

Currently at DiceMax: The interface seems OK and is user friendly, but won't say it's the best. A bit laggy. Would have been better if it was a bit more smooth. The house edge is good and the jackpot system is a great way to reward users.

So you are saying that he is doing this to prove others that he owns the address? Well that is suspicious, but I don't think people would be that stupid. They could just ask for a signed message to prove ownership

If he kept playing, he might have lost all he had won. Don't think it would be worth taking the risk since he already got x4 his initial deposit. Took a good decision by withdrawing. 

You should try your luck now at crypto-games. They have various games like dice, blackjack, videopoker, plinko, lotto, slots and roulette. They are very trusted and deposits are instant. Dice has jackpot and monthly wagering contest too. They got faucet up to 20k+ sat. You need to  level up to reach those claims. Think of it as a VIP program. 

And you judge people based on just 1/2 posts?
What mistake are you talking about? Users were never banned for scamming. They were just tagged. This is what i said.
Scammers before being tagged by staff only vs scammers now being tagged by the community. Which one do you think is more efficient way to tag scammers with no chances of being biased?
If those words "trade with extreme caution" along with some negative red numbers right beside the word "TRUST" which is clickable and shows a list of offence executed by the user does not get your attention and makes you more alert, then you sir deserve to be scammed.
No one said it's impossible. It does take more work - more USELESS WORK. You ban a scammer, the scammer comes back with a new account or buys another account. Ban him,  he comes back again. He will never stop. Making an account takes less than few minutes. So why waste precious time and resources banning him while you could utilize your time/resource doing something more productive, something more useful. Once again what you are suggesting is not an efficient thing to do. Using the ban hammer is not always the solution.

does it bother you to have a fool as your intellectual superior? Think twice before calling someone a fool. It takes one to know one  

If i were to judge you based on your posts above i would say you think conventionally only.
