Is ther anyway to send a fake bitcoin?

(I will be prefacing my post's on here with the following disclaimer until I am more knowledgeable in the realm of cryptocurrency and it's underlying technology, I am new and I do not claim to be a expert)

Theoretically, it should not be possible to send a fake bitcoin nor to add an improper/falsified transaction to the blockchain ledger.

from my understanding the way it works is like this,

>>> You have a crypto coin, for the sake of explanation we shall call this coin a "AsanaCoin"
>>> "AsanaCoin" run's a certain cryptography which add's the security factor to the crypto coin
>>> "AsanaCoin" does an ICO (Initial Coin Offering) which is very similar to an IPO (Initial Public Offering) of a stock
>>> "AsanaCoin" will require a network of computers which is utilized to do several important things
* This "AsanaCoin" network aid's in decentralization of the coin, no one node controls the network which in return removes control of the coin from any one node
* 2nd, this "AsanaCoin" network aid's in the formation of a ledger which keeps track of everything related to the coin itself (it's number of coin in circulation, it's market share, it's transactions)
* 3rd, this "AsanaCoin" network allows for the proper growth/amending of the blockchain which in essence verifies all transactions

now, to give a better example. let's say You and Me would like to do a transaction in which "AsanaCoin" is being transacted between you and myself.
1st = I put in a buy order, let's say I want to buy 100 "AsanaCoin" at $1.00 USD per coin
2nd = You see this order placed on the exchange so you want to make the sell, therefore you place a fill order of 100 "AsanaCoin" at $1.00 USD per coin.
3rd = The order is filled, and the "AsanaCoin" transfers from your wallet to my wallet

within those 3 steps, the first 2 are only tracked by the exchange site. while the 3rd step is added to the blockchain's ledger which is propagated throughout the entire "AsanaCoin" network and becomes permanent history of the coin itself. the blockchain + cryptography + ledger = immutable chain of data.

......

So no, by theory and by design it is suppose to be very very difficult to manipulate a coin's DNA(Blockchain, Cryptography and Ledger) to send counterfeit coins. but just as with anything else dealing with technology, it can be cracked and broken into but it hasn't been demonstrated yet, and if it has it has been kept quite.

I hope this helps your understanding. and if anyone else who has more knowledge than me can see somewhere where I was incorrect in my explanation please feel free to make the correction as so me and asanasuoooos can learn.
