Re: Do altcoins effectivrly "dilute" the 21 million BTC limit?
No, it won't. BTC is BTC and all other altcoins are well "alt"-coins, they are essentially a different currency. It's the same thing as there are USD and GBP, but neither of them dilutes either of them.
That limit is almost 21 million BTC (minus a few Satoshis).
Why minus few satoshis? Isn't the limit exact 21 Million BTC? As far as i know, a miner is not forced to add 12.5 BTC reward as coinbase transaction (at current block reward), only blocks where the reward + fees exceed 12.5 + sum of the fees of all tx's in the block are rejected.
here you go, one satoshi lost forever:

This block alone limits the total BTC ever in circulation to 20.999.999,99999999 satoshi's
