Be careful as trading successfully requires knowledge and practice. The trading market is occupied by very large players who are just waiting for newbies to come in and throw their money away by trading aimlessly.

You can invest in mining but it is only profitable if you invest in large scale at the moment.

Never fall victim of any cloud mining as they are scam all of them.You will only lose money by following this road.

Be careful from the bitcoin double sites or generators,they are here only for a reason, to steal money from people new to bitcoin.

The better alternative is always the one less talked about, buy bitcoin and hold.

Selling,that big thing which makes all of us happy when we sell above the price we have bought and that is how trading started in ancient times.
Coming back to our times you can do this,use programs for technical analysis, you need to analyze trends at different time-frames. Look at the 4-hour chart, then look at the chart for the day,then a 3-day time frame, and make a complete picture of the current price trend. Then make a decision.A sharp jump in the currency by 40% or more during a day is probably a pump. Higher the pump is, stronger the currency will fall
A good strategy is to buy some at any current level and then wait, if dip buy again if pump sell your bitcoins.
Another not verified fact is that bitcoin pumps when more people are into mining and now is summer so all school boys from information technology colleges are surely getting into it.

When I first read about Brave Browser I immediately thought of some sort of "cheat scheme" like thepiratebay torrent site where they use your processor for mining monero while you are viewing their website.I saw the other post which says it can earn you some free btc so I am going to check that out too.

Do you sell a single one ? Is it 40 including shipping anywhere in the world ?

Maybe he just likes to talk shit about cryptocurrencies as he really does not understand a thing about bitcoin.

Paypal will always side with the seller and when you are dealing with cryptocurrencies even more.Paypal is always risky for the seller as once the bitcoin is sent it cannot be reversed, paypal payment can be reversed.That is why Paypal deals are seen as skeptical from most users.

I just downloaded the latest version by clicking your link which points to the official website.I used a virtual machine just to be sure and it all worked normally.I don't think it has any problems or any trojans there and most probably your Bitdefender is not as good as an antivirus as you might think.

The police will only help you if Bitcoin is legal in your jurisdiction, in you country.If it is not legal then the police can't do much and beside that it is very difficult to track where the money have gone.

I was once scammed by an Indian which offered to send me 6 pcs of Iphone 7 a few years ago for just 1000 dollars when the price of one Iphone was about that price.I received an empty box of one Iphone 7 and there was nothing in it.I learned the hard way and I feel great that I just found a forum which sells cheap hardware for mining and there are people safeguarding it.
