=====================================
Bitcoin Block Halving prediction
=====================================
bc=923744
gbt=1231006505
bbt=1763215282
This is average time to mine a block
(1763215282-1231006505)/923744
bts=576.1425252640068417149754
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Mon Mar 6 11:58:52 UTC 2028
-------------------------------------
Next palindrome will be 924429
predicted to happen at this time:
Thu Nov 20 03:38:59 UTC 2025
-------------------------------------
Current mining epoch number is 458.
The next fortnight happens in block
925344 and probably around this time:
