All blocks with a block height less than 6,930,000 are entitled to receive a block reward of newly created bitcoin value, which also should be spent in the coinbase transaction. -------why the num is 6930000?

In ~200 years due to the way the amount of acceptable new coins in coinbase is calculated would reset and new BTC could be created again.

I am sorry for that I still cannot find where the 6930,000 is mentioned? could you tell me how to compute it?
@philsong Initial Block reward of 50 BTC rightshifted 32 times (= 32 halvings, or 50/(2^32)) = 1 Satoshi. 50 BTC rightshifted 33 times = 0 Satoshi. So mining rewards are naturally 0 after 33 halvings because of limited precision. 6930000 / 210000 = 33 (a halving happens every 210,000 blocks).
good comment above, thanks
