=====================================
Bitcoin Block Halving prediction
=====================================
bc=967261
gbt=1231006505
bbt=1789550159
This is average time to mine a block
(1789550159-1231006505)/967261
bts=577.4481515866435360843287
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 08:47:21 UTC 2028
-------------------------------------
Next palindrome will be 967769
predicted to happen at this time:
Sat Sep 19 18:45:02 UTC 2026
-------------------------------------
Current mining epoch number is 479.
The next fortnight happens in block
967680 and probably around this time:
Sat Sep 19 04:28:29 UTC 2026
