If the company were to shut down or the website, would I lose all my money invested into it?

Wow you guys are awesome! I really appreciate you all looking into this site for me for real!
I live in America and already have USD so I will not be transferring anything to USD. The reason I was saying USD is because this is a btc site and I wanted opinions on the future of USD just to know if it is worth investing in.

Someone mentioned that USD is "strong", therefore it is really risky. I thought if the currency is "strong" then you have a better chance of profiting?
Someone also mentioned ETF (I don't understand this) but in an article about the site it says that Betterment handles ETF:
"Betterment will build you an efficient portfolio comprised of widely diversified, low cost ETFs. If you don't want to manage your own portfolio, or hire a financial advisor, Betterment is tough to beat for the very low price."

I am sorry if this is in the wrong place, I really know very little about economics/financial stuff.

I am 23 and a college student and a part time employee and my annual income is around $7,000 (I focus more on school right now than work).
I have always wanted to learn how to invest but every time I try to research I get overwhelmed and it feels too complicated to me. But then I found this company website/Iphone app called Betterment and have been reading a lot of good reviews about it both from the App store and on websites. (I am in no way advertising this or spamming, this is a sincere post) Basically it manages your portfolio, it helps you set a goal and gives you advice on what to invest in and everything is just done there and to me it actually looks doable for once. The fees are really low and based on your account balanced. Basically if I start with $50 the monthly fee is $0.02 and if I had $30,000 in the account it would be $6 a month.
But here is also a general warning given in an article about it which scares me:
"In this Betterment review, I have to provide a common sense reminder. Like all market investments, Betterment’s stock and bond investments are subject to market risk. If the markets are up, your balance will likely grow. When markets go down, your balance will likely shrink. You have no guarantees and Betterment is not a FDIC insured savings account.

If you need your money in the short term, a savings account might be the best place for it, because you’re guaranteed to get back the the same dollars you put in (known as your principal).

When you invest in stocks and bonds, risk is present and you can lose money. The fact that you are taking more risk also means that you’ll likely earn higher returns over the long term."

So this statement made me want to ask you guys that I assume are more experienced investors, is it too late to start investing? Do you think the American or USD economy will crash drastically soon and is it even worth it???
Would you recommend this for a beginner.. trying this site?

BTW here is the article review I looked at:
http://cashcowcouple.com/service-reviews/betterment-review/

EDIT: This site is appealing to me because they apparently no longer have a minimum starting balance and having very little money I could start with a very small amount.
Basically I want to know if this looks like a legit, safe, and good site for a beginner like me from an experienced investor.  Also, does it look like I can take out money from profits at any time? Or do I have to keep money in my account and not touch it? Idk these things.

I claimed my 2500 nxtty coins or whatever they are called. But I am looking at this app I personally don't really understand it and when I click on my wallet I don't see an account balance or anything. I will try to figure this out though.

The app updated yesterday and now it goes to the Alias page, I have it set up now.

Hey sorry I kind of gave up. I am laying down now about to fall asleep I will see if I  can take a screen shot tomorrow. Its a red page asking for email, password twice and I think something else. The very first page that showed  when I downloaded it and opened it for the first time. I filled it out assuming I was registering and when I clicked log  in a please wait message showed with a spinning circle appeared, then it went away and the same screen was showing with filled out information. Won't go past it.

I'm sorry but I can't get past the first screen.

Hey I just saw this and checked it and I was able to download it now!! =)
Except... I am stuck on the registration screen that comes up when I open the app. I filled out the information but when I click enter it says please wait then the please wait goes away and the registration screen just stays there.

I'm sorry I looked there and can't find it =\
This 5.0  version of android has made my tablet run slow and things keep crashing

I looked in my "about tablet" section and it has various information such as model numbers and IDs but I do nor see "IMEI".
Is there another name for what you need or anywhere else I should look?

Hey there, just letting you know I updated my system today  on my nexus 7. I have 5.0 lollipop.  It still says not compatible  on my device.

I think he was being sarcastic because dollars are the best way we  can measure/understand the value

Can you maybe message me or let me know here when it is updated? I can try it on my device and let you know if it works.

Okay thanks,
I still don't understand but good enough for me. Lol

Sorry this is probably a stupid question but I really don't know can someone briefly explain what "Bitcoin Core 0.9.3" is for me? Every post I look at about it assumes that everyone understands what it is. Is it something that I need to have if I have bitcoin? Who is the person that updates these things and "regulates" the bitcoin system?

Thanks! I just don't want to miss out on the coins =P

Awh I have the newest android on my nexus 7 tablet but it says my device is not compatible with this version =(
I don't have a smart phone!

Edit: I have Android version 4.4.4
Kernel version

Thank you so much for the reply bobster! I really appreciate it a lot.
I guess I won't try to get into it then, I guess I am just searching around for ways to maybe make a little bit extra money.

I am fairly new to cryptocurrencies and I do not know much about how mining works.
I am wondering since it seems no longer worth mining BTC with a generic computer, are there any Altcoins that possibly have potential that I could mine while at work and while sleeping? Or do I have the wrong idea how it works?
I don't know what I need but my computer I think has a quad-core processor and 4gb RAM.
If anyone can suggest altcoins and how to get started I would appreciate it. =)

Also, I have been reading through these forums and I am wondering, are most of the altcoins being advertised by people that created them themselves for their own benefit? I just can't tell how legit some of these posts in the altcoin section are because everyone is really trying to sell their favored altcoin.
