Is it really good since we all know that everything on internet can be hack or something....
Is bit[Suspicious link removed]d to make your money grow fast or will you just lose all those money??
First of all, most people here on bitcointalk consider bitcoin as "real money." Most of the people here probably consider it as more "real" than fiat money. Secondly, yes, lot's of technology can be "hacked" but bitcoin is different. Because bitcoin has a distributed ledger that is downloaded to computers all over the world, and because every bitcoin (or fraction of bitcoin) can be traced back to it's creation (coinbase address) it can't be "hacked" or duplicated. It really is an ingenious invention.
