=====================================
Bitcoin Block Halving prediction
=====================================
bc=949247
gbt=1231006505
bbt=1778695040
This is average time to mine a block
(1778695040-1231006505)/949247
bts=576.9709654379045307443365
Now let's multiply that by 1050000
which is the block number of next
halving and get the prediction:
Thu Mar 16 13:36:35 UTC 2028
-------------------------------------
Next palindrome will be 949949
predicted to happen at this time:
Mon May 18 10:27:53 UTC 2026
-------------------------------------
Current mining epoch number is 470.
The next fortnight happens in block
949536 and probably around this time:
Fri May 15 16:16:24 UTC 2026
