hello everyone!
few days ago my friend told me to create account on cryptoesto.com because it is better than other exchanges. I was created new on cryptoesto.com and also i am hold 10 btc in my walllet.Now the cryptoesto site is not available on google

can anyone give me personal opinion what i do now

Are you kidding? This looks like fake, as you are a newbie then how come you had 10btc? I am damn sure you are lying because even a .50 BTC holders have a lot of knowledge in cryptocurrency and you are blindly posting such stuff is not at all possible.
Never think that OP is kidding because, is very much possible for him to be in possession of such amounted Bitcoin 10BTC. There are some investors who have been on cryptocurrency but yet to create account on the forum. Few years back i had to joined the movement of Bitcoin through localbitcoin and never had of this forum so, also others who have acquired some Bitcoin before the awareness of the forum.
