Nope, including the lost Bitcoins they will be all 21 million.
To be more accurate:
The exact number of bitcoins (including the lost ones) will be 20999999.9769
Yeah, thanks. So, all are estimation for the year but likely to hit exactly and for this quantity of Bitcoin.
Sadly , I've added more lost coins than I'd care to admit. I heard about Bitcoin in 2010 and decided to start mining while at work . Did so for about 3 years till I moved and got about it . Never found the wallet.dat files 6 years later when I went looking. The bitcoin core wallet showed 2,100 encrypted files ( not sure if that is transactions or what) if transactions there's no telling how many coins as my PC would have been clearing 3-4 BTC solo mining in a day
You this too early? I cannot believe those stories, but it doesn't mean they're not real. Well, I've read the same experiences about those who have known Bitcoin too early, mined a lot, and then just forgotten the wallet.dat. Same same stories.
But it does happen, I guess a regretful part is waking up almost every day.
