No, is not the END. No one can stop bitcoin or any other cryptocurrency right now!!
They can set bans at country levels, they can raise testimonials, like someone from some bank did last week!!. They can arrest people and close brokers, they can do whataever they want, but, nothing of this will end cryptocurrencies!!.
They can try, but will fail every time.
Now is a great example of this, just look at the cryptomarket. Yesterday all cryptomarket was crashing 20%, now, is 10% green again, and raising fast!.
The only way to stop bitcoin right now is shutting down all the INTERNET!!!, and this i´m pretty sure will not happen!!

Does Bitcoin present a threat to sovereignty, control of the domestic money supply, borrowing, inflation, foreign exchange or fiduciary institutions? Yes and No…

Gradually, lawmakers in some countries are beginning to perceive Bitcoin as more of an opportunity than a threat. There may be no need to dissuade citizens from adopting Bitcoin, even if the populace saves or spends it as actual stored-value cash and not just as a payment instrument.

No government can effectivily ban bitcoin (or any other digital record keeping system). They can ban exchanges and thus create another huge ilegal market, for only criminals and terrorist to use it. Governmets don't know yet, but their mafia taxing methods, money printing business and totalitarian money controls are coming to an end.

The governments can’t ban something they can’t control, if they would like to destroy it, they would have to erase every node in the network which is nearly impossible - All the computers which contain the blockchain history need to be put offline.

You can find an ocean of articles, videos, news, applications, and websites that are all focused in educating people about cryptocurrencies. My point is, you cannot learn everything at one center because, every cryptocurrency follows different rules and that rules vary from country to country. If you want to learn “how cryptocurrency works in India?” there are a whole lot different articles and videos on that. Similar is the case with France, Japan, and so on.

Your question gives me an idea that you are either a beginner or got scammed by some frauds. You see, there are some courses available where experts guide you on investment plans, mining techniques, and various methods of using these coins but, the wisest decision will be to learn by yourself. Seek an expert advice and start on your own. This way, you learn what you experience and as they say. “Experience is the greatest teacher”, your experience will never let you forget any term or method.

Join BTCMonk and you can get all the necessary information about bitcoin and other currencies too. They offer numerous currency options and guide their clients/customers for a safe investment plan.

There are a few ways to earn cryptocurrency.

You can:

Mine Your own coins - Generally use ASICS and customized GPU/CPU miners. Some popular coins to mine are Bitcoin, Litecoin, Ethereum, ZCash, Monero, and Dash. If using your desktop/laptop you will not generate a significant amount of income and electricity costs may out weight any gains. Regardless, you can use MinerGate to easily mine cryptocurrency on any computer. Likewise, you can also invest instead into Cloud Mining Services. But beware, there are not many legit companies. A few I could recommend would be Hashflare, Genesis Mining, and Hashnest.
Buy/Trade to earn coins - This is the hardest but most rewarding method. Learning valuable skills such as Trade Analysis and keeping up-to-date on current information and trends is extremely important. Good exchanges to start out on are Binance, Bittrex, and GDAX. Getting yourself familiar with trading bots is also a must. I personally use Cryptohopper as is is fairly easy to customize for beginners and with the right management can easily do 1.5% a day (unless running it on a bear market). However, there are many others out there, each with their own advantages and disadvantages.
Claim coins from faucets - Many websites will pay users small amounts of cryptocurrency for completing Captchas. Generally will be able to claim anything from every 5–60 minutes. One of my favourites is FreeBitCo. You can claim every 60 Minutes for a chance to win up to $200 in BTC. They also offer a Dice Game, Mining, and Weekly Lottery. There are however, many faucet websites out there. The problem with many though is many will have high withdraw requirements and other barriers so you will never actually see the funds. Always keep this in mind when Choosing faucets
Complete tasks/Surveys/Videos for free coins -EarnCrypto will pay you in the coin of your choice for doing simple tasks such as watching videos, installing apps, completing surveys and doing micro tasks.
Participate in free token airdrops/promotions - Many coins before they go live will do Initial Coin Offerings and Airdrops to promote their coins and raise investments. This is a good time to be able to receive some free coins that could potentially have massive future value.
Promote affiliate links that pay in cryptocurrency - As cryptocurrency emerges, so does a new class of affiliate marketers with new programs and products to promote. If you are able to target the right Niche, massive gains await.
Complete freelance services for cryptocurrency - If you search online there are many communities that will pay in Bitcoin, Ethereum and other currencies for services

You can verify that address in Blockchain Explorer like Blockchain.info.
After visiting Bitcoin Block Explorer - Blockchain website you can paste that wallet address and after that you are able to see How much balance have in that particular wallet.

In any technology, work for developers kick in when customization is needed. Standalone blockchains like hyperledger can be installed and started by IT admin but to get any benefits out of it, developers has to work on code side.

In blockchain, customization can be carried out on tasks such as

Smart Contracts
Distributed ledger
consensus algorithm
membership services
Identify management
These tasks are coded in chain code as per business requirements.

So, to talk about the future of developers. It's safe.

More likely than a double-spend hack is that the perceived anonymity of bitcoin transactions will be "hacked" via traffic pattern analysis tools.

Every transaction is public forever, and it's quite easy to follow the correlation of keys to individuals with a little bit of code.  Bitcoin's nowhere near as anonymous (or even pseudonymous) as people treat it.

It's not. Even sending coins through tumblers has proven to be traceable. The best way to make your coins anonymous is to send your btc to shapeshift and convert them to xmr. Then send the xmr to xmr.to and get bitcoins out the other side.

Btc is worth a great technology(in my opinion)

Simple

Buy low Sell high

Dont sell if you are at loss.

Thats in my opinion.

Happy investing.☺

Nothing is “safe” when it comes to Bitcoins or any other Cryptocurrency for that matter.

The price of Cryptocurrencies are driven on market speculations, and trading demands. One must have an appetite for risk taking when it comes to investing in Cryptocurrencies.

If you are looking to invest into it, my suggestion would be only invest the amount that you won't make you feel bad in case you lose it.
