Well, someone got a little tempted with their facilities to mine. Imagine using government-used supercomputers mining bitcoins, you would make a whole bitcoin I guess in a matter of minutes! It's cool, but, you'll get in trouble for it. The guys were immediately arrested though, so they didn't get the crypto they wanted.

Full story is in here:

Hi!
It's a very good question. Thank you. Here's why NVT are expected to go up in price:
One of the way for that is to expand the number of partners using Naviaddress, like UBER or Booking.com (they are our partners already), to incentive the NVT circulation.

The other one is to burn tokens. We plan to sell 20-30 country and regional containers to local country partners. This may result in burning from 100 to 300 mln NVTs by 2021.
All nominal price in tokens for sold naviaddresses will be BURNT by the platform while the premium - a diffrence between market price and nominal price will be retained by the platform as revenue.

Sell all premium country/regional containers of naviaddresses for Navitokens through auction.

   First of all make yourself sure you keep your BTC properly, dont use online wallets for that. Use Ladger Nano or Trazor as HeRetik said, if case you dont want to buy hardware wallet run Bitcoin Core on offline computer, connect it to internet in only case you want to make a transaction.
   You can trade your coins on Bittrex or Polonex, you can buy not only different currencyes but also tokens, some token prices behave differently compare to BTC price, so you can make profit this way.
   But actually our motto is HODL, it means keeping BTC forever 

Altcoins are alternative cryptocurrencies such as Ethereum and Litecoin. If you don't know yet what altcoins are, I'd suggest staying away from them until you have read up on the matter.

Given that 0.5 BTC is no chump change, I'd recommend getting yourself a hardware wallet such as the Ledger Nano S or a Trezor.

Buy one of these wallets directly from their stores, not from any third party resellers or eBay:
https://trezor.io/
https://www.ledgerwallet.com/

For all intents and purposes, both are effectively equaly secure. Ledger is slightly cheaper. Availability may vary.

Read up on how to use a hardware wallet. Keep your wallet seed back up secure and offline. Remember that every transaction you make is irreversible. Maybe play around with small transactions before moving everything onto your hardware wallet.

Keep your money off exchanges. Stay away from cloud mining. Stay away from ICOs and alts until you really know what you're doing. Daytrading is a great way to both make and lose money. Remember that trying to get rich quick is a great way to get poor quick. Not losing money on scams and pseudo-investment is half the battle.

There are several options:
1. Do not do anything and wait until the price of bitcona increases
2. Scalping-trading strategy that attempts to make many profits on small price
    changes
3. Invest in altcoins
The last two options require a lot of knowledge. Learn as much as possible. Choose the method that's right for you. There is no single best way to earn a crypto.
