So can anyone inform me on some Ico they've invested in and if succesful what ROI they had ?
I'm currently invested in one ICO with a very small stake , around 20 $ worth of bitcoin just to see how it goes.

It's funny how everyone here that's suggesting to ban signature campaigns are all enrolled in them.

And last week there's a guy who won 0.008 with just 32 to lottery tickets , I can imagine the frustration on the people who bought thousands of tickets or hundreds of thousands of tickets without winning anything 

Can someone point out to me one exchange where these currencies are available for trade ? Honey , GB , Hyper ? And some wallets for them ?

Legit cloud mining site for now , will pay you , not sure you will return your investment even in 1 year , but if you're just looking to invest to see how it goes , I suggest you invest in a very small way and make your conclusions after.
Though I think everyone will agree that cloud mining is not profitable.

So how you can see at the time you were thinking of investing 2 months ago the bitcoin price grew until now 2.4 times , so in 2 months you could've at least double your investment , but at the same tame the price could've went down .
My personal oppinion  , just invest in some alt coins which you consider that they have potential , that are worth much less , so you can make a much smaller investment and possibly make much more profit than you could make on bitcoins.  For example a coin that now is worth 10 $ in a few months it can be worth 100 $ , so your profit will be X10 , which with bitcoin I doubt that it's value will rise 10 times considering now it's 2.400 $.
So read a little , study the market and after decide which option is better.
There's always a risk in any investment , otherwise I suppose all of us would've been rich by now , so just invest what amount you are willing to lose , and look forward to what you can earn.

GPU mining is long dead , you are a few years too late , which in bitcoin years it's like decades , better with the money you wish to invest in a pc for mining , just invest them in some coins , there are plenty of alternatives out there which you can buy and later on when the price is right for you  to sell them on the market and make some profit , though I suggest you to spend a few days/weeks to get more acquainted with what BTC and alt coins are and how you can profit from this.

Or just hold on to it as it's speculated in the following years the price will continue to grow , altough for 0.1 btc the profit will not be so much.
Another option is to invest in altcoins but you need to study this really well and get acquainted with all the factors.
Personally if I were you I would just split this 0.1 btc in a number of different altcoins and see where it goes from there.

Is it better to accept bitcoin as payment ? From what I saw I think the payments they make for services in bitcoins are less than payments you would receive in $.  Isn't it better to work online and get paid in $ and after just purchase your own bitcoins ?

Considering last week 200.000.000 tickets where bought , I would like to ask you how many tickets you purchased for this lottery , I suppose if you only claim the bonus the answer is not a lot , so think of it , you're playing for 6 months so u participated in roughly 26 lotteries until now , with probably a 0.001 % to win something , I mean you can play for years and most probably you will not win anything , but if you want to increase your chances save your satoshi's you receive for around 3-4 months and after exchange them for lottery tickets.

What are your speculations on the bitcoins but also the rest of cryptocurrencies in the future ?
Me personally I think that it will generate more interest and at one point it will become a stable currency acknowledged worldwide , so when more countries accept it like currency it will increase the demand considerably thus so it's value.
I understood for now Russia and China acknowledged bitcoin like currency ? Am I wrong ? And are there any other countries that did the same ?

Well early I think would've been considered when the bitcoin was worth aroun 5 $ . But still even now if we take in consideration the steady and increase of popularity of bitcoins crypto currencies is a good investment to make even at this stage when 1 bitcoin is worth around 2500 $

Can anyone inform me a little on the ICO market ? Basically it's an investment that can bring profit or not bring anything, this part is clear.
I would like to know if there are any trusted ICO's out there and not just the regular runners with the investments.
Has anyone here had any substantial succes with any ICO ? Like you invested in some ICO when the shares were costing close to nothing and now to be worth a lot ?

Si ce anume va scrie in declaratia de provenienta a banilor ?  Cum putem justifica bitcoins in o astfel de declaratie ?

I don't think it's possible for someone to send you 1 or 2 satoshi , as the fees for transactions have a lot more zeros added to them so basically it's not worth it.
You can try some faucets but even in them you need to acquire a number of satoshi to be able to withdraw it to your wallet , but you can do this in a couple of days.
If you want to check some of these faucets check my signature , I have there around 4 faucets that will make the payments. Good luck

So it took you around 7 months ? And this I suppose it was when the bitcoin value was much lower than now , I think through faucets there is no real way to actually earn 1 bitcoin , unless you're the owner of the faucet.
How much was the bitcoin valued at when u achieved your first bitcoin ?

Maybe last year you could have done this , but now ? I don't think there are any faucets out there which can pay you 100.000 satoshi per day unless you are already established with a big number of refferals.
I mean look I will give you an example , one of the best faucet sites freebitco.in is offering you around 73 satoshi per claim , which you can claim every hour  , so if you manage not to sleep for 24 hours and claim the bonus every hour you will get around 1700 satoshi.   So for anyone trying to make money out of faucets it's not worth it unless you find a faucet where u don't really think about the bitcoin you receive and more about the gameplay.

But I think there are also lots of examples of ICO that are scams ?  Basically there is no assurance that investing in an ICO is legitimate right ? I mean what's there to stop them to run with all the investments ? ( probably the same like cloud mining ? )
Anyway can someone give me more information about ICO's and some trustworthy platforms to invest in them ?

Asta daca v-a scadea , dar e totusi posibil sa continue sa creasca . Sunt convins ca acum sunt x persoane care regreta ca nu au investit in bitcoin cand valoarea lui era 200 $ ( inclusiv eu ) , deci chiar daca pretul e acum 380 $ cred ca e ok sa investeti in Eth in momentul asta.

So than I would like to ask , what can push the bitcoin price a lot higher ? I suppose countries accepting it like local currency will make it's value sky-rocket right ?
