Nowadays there are very developed Windows viruses and malware, which download through Youtube, porn etc., even software download. So only Linux can help, because Windows viruses and malware can not download in Linux. Best of Linux of course is Debian - check this OS here https://www.debian.org/. Especially Debian have nice support through Debian Wiki etc. Plus all Linux OS are free of charge. 

You will get either virus or malware with time, because of watching things like that. Neither good antivirus, neither virtual machine will help. Nowadays there are very developed viruses and malware, so you need very experienced computer man, which can suggest you the right way - and it is not easy. 

Doge, ETH, Monero will survive long term, regarding Litecoin - hard to predict. Most probably from all altcoins will survive 5 - 6, not more, because all altcoin market is not so large, like Bitcoin market. 

If ZCoin will offer full anonymity, then it can have future. Currently only Monero offers something similar, so no strong competition in fact. 

You can start with 1 USD in Bitcoins with this company - https://www.fxopen.com/ and firstly look for trade some weeks before any trade, and then try to buy at low and sale at high.  

What they will do, if they loose ? Buying stocks not always give profit. They will buy a lot and then loose all investment ...  Just imagine how angry will be Obama in Whitehouse, when receive news, that Fed loose some hundreds millions yesterday. 

As far as I know only Monero is really anonymous, therefore it price go up. So if you buy Monero now, probably after few months Monero price will be much higher. 

Only this gambling site - http://www.bitcoinbetting.website/, others have ~ 1% house edge. But even with 1% house edge you can win instantly. 

Bitcoin/USD forecast would be important, and may be also some altcoins too. FIAT pairs can be optional only. Most traders make buy/sale with Bitcoin only. 

TOR search engines, like Grams, all work very similar - from search you can get only some deepweb marketplaces ads. In practise TOR deepweb is not usable for average Web user. Google is much better and can find everything. 

Dice win comes with gambling experience, of course there are also dice sites, in which you can win faster, but most important is good experience. WIth this you can win almost in any dice site. Chat with other players in gambling chats and you will see

I think the best is Poloniex exchange, this is large exchange - online around 7000 people, plus you can also search in the forum regarding this exchange too, check here - https://poloniex.com/ 

Waterproject is the best for funding. Help for people in Africa is important because, otherwise this continent is very poor. 

Most possible you will just invest your BTC in someone and never get back, that type pyramid sites do not work nowadays. You can not get your refferals, so in fact you just invest and that's all. 

Original protection against various cryptoware, like cryptolocker etc., download for free, over 1 millions downloads already, for Windows XP, Vista, 7, 8, 8.1, 10, manual update ( auto update in paid software versions ), works with existing antivirus & antimalware software, check this link https://www.foolishit.com/cryptoprevent-malware-prevention/  

These rules will give the FBI authority to hack millions of people's computers with a single search warrant in any country. The FBI will be permitted to hack into a person’s computer or phone remotely and to search through and remove their data. The FBI will be able also to introduce malware into computers.

This dice site offer Doge, and also Litecoin, Bitcoin for playing - https://www.999dice.com/ 

I think that exchanges do not add fake transactions, only so called BTC doubler scam sites can add fake transactions. But you can search in the forum largest exchanges, and then trust only to largest BTC exchanges - check their websites too. For example Poloniex exchange - https://poloniex.com/ have current online users counter. 

I will give you really good BTC project idea - multi crypto desktop wallet with Bitcoins, Litecoins, Doge, Monero, ETH etc. coins, so you can send/receive them from your desktop. Currently there are only some Web online multi currency wallets.  

Currently there are only some Web multi currency wallets, but not desktop wallets. Developers can not make them, because it is very hard to do such multi currency desktop wallets, but in future may be some of them will make, let's hope.
