I'd suggest you start here: https://bitcoin.org/bitcoin.pdf to learn how Bitcoin works.
Bitcoins are real.

All software is like that, you can't deny the usefulness of the Internet or computers, it is not virtual reality, it's software, virtual reality also made with software and computers.

If you can buy beer with it, it's real.

firstly
bitcoin is not like fiat with a central database that can be hacked/manipulated. its a local database with many mechanisms, which is then verified and check by/on thousands of people computers that sync as a network to check everything everyone has is the same

you cannot simply add a couple zeros to your 'balance' and become rich.

bitcoin is way way way more complex.
there is no 'account'/'balance' to hack.
there is no single location to manipulate to affect the bitcoin network

bitcoin at code level is a ledger of from A to B transactions and holds all the value movements since creation.
the front end graphical user viewing side displays it more simply as a total. but this total is not in bitcoins ledger as a total. its just a local calculation a persons pc does for viewing pleasure.

if a person tried to change the total or spend more value than what actually exists in the ledger that spend is void.
there are many checks and double checks and triple checks (thousands of checks infact) to ensure nothing can be edited in.

in short if one person rewrote their ledger. the other thousands of checkers would ignore it, because it doesnt match their versions of events(ledger)

---

however with that said
many scammers can con someone into downloading an altcoin program and make the victim believe the program they downloaded was bitcoin. but people can simply check an address/transaction using one of the many public 'explorers' to see if that transaction/address is a real bitcoin transaction or not.

in short if its not on the bitcoin ledger it doesnt exist.

there are many mechanisms that secure the ledger and many mechanisms to ensure everyone in bitcoin has the same ledger. if someone was to break the mechanisms all they are doing is creating their own altcoin which other bitcoiner would ignore

They had almost 10 years to hack it till now, but no one has done it yet. Don't mix trade platforms and Bitcoin blockchain hacks!
You must know that there are many people who will ''defend'' BTC too, not all want to just hack it and destroy this.

so is more than 90% of fiat currencies. it's just numbers sloshing around the system that people swap. the reason they have value is because people choose to give it value. same goes for bitcoin.

there are thousands of other coins all attempting to do what bitcoin does. they're worthless because there ain't widespread agreement that they're worth anything.

I don't know what you mean, how could anyone fake Bitcoins. You mean by counterfeiting or what? This is not possible. Or faking the balance..Bitcoin is functioning in the virtual world but still it's arthur good protected and it's.not easy to manipulate with network and fake balances.

Bitcoin is very real and we can see the reality of it by the high trading volume of over 31b dollar. We should know that what ever is good people will always try to faking many services and product in other the get what they want since they can not get it in the right ways.
