=====================================
Bitcoin Block Halving prediction
=====================================
bc=968175
gbt=1231006505
bbt=1790106345
This is average time to mine a block
(1790106345-1231006505)/968175
bts=577.4774834327642907901042
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Wed Mar 22 17:20:40 UTC 2028
-------------------------------------
Next palindrome will be 968869
predicted to happen at this time:
Sun Sep 27 11:05:14 UTC 2026
-------------------------------------
Current mining epoch number is 480.
The next fortnight happens in block
969696 and probably around this time:
