=====================================
Bitcoin Block Halving prediction
=====================================
bc=949375
gbt=1231006505
bbt=1778769545
This is average time to mine a block
(1778769545-1231006505)/949375
bts=576.9716529594175542672239
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:48:37 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 10:38:46 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 16:27:17 UTC 2026
