=====================================
Bitcoin Block Halving prediction
=====================================
bc=861183
gbt=1231006505
bbt=1726255617
This is average time to mine a block
(1726255617-1231006505)/861183
bts=575.0793233501783590963139
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Tue Feb 22 13:52:49 UTC 2028
-------------------------------------
Next palindrome will be 862268
predicted to happen at this time:
Sat Sep 21 00:46:18 UTC 2024
-------------------------------------
Current mining epoch number is 427.
The next fortnight happens in block
862848 and probably around this time:
Tue Sep 24 21:25:24 UTC 2024
