=====================================
Bitcoin Block Halving prediction
=====================================
bc=969920
gbt=1231006505
bbt=1791156880
This is average time to mine a block
(1791156880-1231006505)/969920
bts=577.5216486703556269015723
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 23 06:13:33 UTC 2028
-------------------------------------
Next palindrome will be 969969
predicted to happen at this time:
Mon Oct 5 07:26:18 UTC 2026
-------------------------------------
Current mining epoch number is 481.
The next fortnight happens in block
971712 and probably around this time:
