=====================================
Bitcoin Block Halving prediction
=====================================
bc=946961
gbt=1231006505
bbt=1777347036
This is average time to mine a block
(1777347036-1231006505)/946961
bts=576.9402901066779870786789
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 04:39:46 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 09:47:44 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 21:05:45 UTC 2026
