=====================================
Bitcoin Block Halving prediction
=====================================
bc=946749
gbt=1231006505
bbt=1777214343
This is average time to mine a block
(1777214343-1231006505)/946749
bts=576.9293245312912595722207
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 01:27:52 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 06:54:32 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 18:12:35 UTC 2026
