=====================================
Bitcoin Block Halving prediction
=====================================
bc=924211
gbt=1231006505
bbt=1763506696
This is average time to mine a block
(1763506696-1231006505)/924211
bts=576.1667139141235993473358
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 19:02:10 UTC 2028
-------------------------------------
Next palindrome will be 924429
predicted to happen at this time:
Thu Nov 20 09:51:40 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
Wed Nov 26 12:18:12 UTC 2025
