Hi guys, I'm new to the world of bitcoin and i found an interesting website that is a browser with mining features and I would like to know if it's safe and if it actually works.
A website that's mining cannot mine bitcoin, since Bitcoin can be mined only with special hardware (which you most probably don't have).
So it may be mining altcoins and sell it for bitcoin, in the best case (I'll come back to this). If that happens, you'll be earning coins that worth some pennies, but your computer will consume electricity that'll cost much more than those pennies, so you lose money.
And I'm back to "it's mining altcoins, in the best case". Since it's very few pennies you'd be "earning" (that's if you ignore the electricity cost) like this, there are (at least) 2 directions for this kind of websites:
* if you're lucky, some will show a lot of advertising and will act like faucets, letting you withdraw .. pennies (after a big threshold is reached)
* if you're not too lucky (and this is what I expect to be the most widely spread case) the website will show some nice numbers there, may even steal all the information it can from your computer or at least browser, but you'll never be able to withdraw (and if you insist, you may be lied to deposit money there - under whatever reasons).
TL;DR:
you better avoid that kind of websites.
