Anyone could give me a valid an information about supply bitcoin? I just did a reseach for an articel for english language but not found. But those with another languange given an explain total bitcoin with amont above.  :-\

I am not sure exactly what you are asking. Are you asking what would happen when the bitcoin supply reaches 20.999.999.9769 or are you stating that based on your research the current bitcoin supply is 20.999.999.9769?

You can check the supply and all other important information on https://coinmarketcap.com/ or similar sites like Coin Gecko.
Btw, the current BTC supply is 17,592,062 according to CMC.

Bitcoin block rewards started at 50 BTC. Every 210,000 blocks, the block reward is cut in half. Eventually, the block reward will be 1 Satoshi per block, after that it's zero and the maximum supply has been reached.
See https://en.bitcoin.it/wiki/Controlled_supply#Projected_Bitcoins_Long_Term for a break down.

So this gets me wondering, What happens when the block rewards are too low to sustain mining?
I know there are some Bitcoin enthusiasts who will continue mining even with zero reward, but they will definitely be few.

1. Won't this lead to problems on the bitcoin network? Like slow transactions and high fee?
2. Is there a contingency plan for this kind of scenario?

Sorry for asking too many questions. Am just curious about the scenario.

There are several topics on this, in case you're interested. Short version: I don't worry about it :)

Transaction speed is defined by the protocol, it's the same (on average) with 1 miner as it will be with a million miners.
Fees depend on block scarcity, at the end of 2017 fees often got half as high as the block reward already.

Yes: fees.

If anything, lower block earnings will lead to a lower energy consumption and a lower drain of resources from the Bitcoin ecosystem to hardware manufacturers and power companies. But high block earnings lead to a high difficulty, and thus secure network.

You can check yourself in Bitcoin code repository in github i think. Its constant value of 21000000 written in Bitcoin code.
In theory anyone can propose to change it, but noone from developers would accept or even if they did, miners wouldn't.

Where did you get that information the supply you are talking about is too much.
If you want to see the correct one check this link https://www.bitcoinblockhalf.com/

So that you can see the right information including the blockchalving countdown

Well,
some says Bitcoin supply is 21,000,000.00.
But you are now going to learn two things:

• reality is way more complex than theory (otherwise life wouldn't be so intresting)
  
• don't trust, verify
   

I tried to craft a detailed post, compelte with formulas and lists, but then I humbly realised I was only retyping this great answer:

Thankyou loyce.
