=====================================
Bitcoin Block Halving prediction
=====================================
bc=946823
gbt=1231006505
bbt=1777259275
This is average time to mine a block
(1777259275-1231006505)/946823
bts=576.9316895220231003861330
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 02:09:15 UTC 2028
-------------------------------------
Next palindrome will be 947749
predicted to happen at this time:
Sun May 3 07:31:53 UTC 2026
-------------------------------------
Current mining epoch number is 469.
The next fortnight happens in block
947520 and probably around this time:
Fri May 1 18:49:56 UTC 2026
