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

Did you research before you buy bitcoin in that website? I don't think so. You trust your friend to create an account, but you are not careful to hold your bitcoin.
A friend can do more than that, and I have seen some person can lie to his friend for money or another thing.
The only suggestion for you is to make sure you research before you do something because if that is your money, you need to have responsibility and handle with care. Don't trust anybody if it's related to money because money can make people change.
