=====================================
Bitcoin Block Halving prediction
=====================================
bc=946962
gbt=1231006505
bbt=1777348039
This is average time to mine a block
(1777348039-1231006505)/946962
bts=576.9407400289134844761622
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 04:47:38 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 09:54:51 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 21:12:51 UTC 2026
