it was here at day one with block one.
it was overly visible - we have at least 15 threads here, it is in the top 15 of coinmarketcap etc. pp.
bytecoin was a premine because it was not announced - they came here with 82% of mined coins.
even the always yesterdays at r/bitcoin were discussing monero as an implentation of sidechains....
But tell me, if Monero ever goes to mainstream, what will be the difference: Monero is not a premined but still like 80-90 % mined vs. Monero being 80-90 % mined due to premine?
Who wants to buy a coin that is almost mined? Even bitcoin has problems to find new buyers and therefore the price is declining month after month.
you don't buy a coin - you exchange one currency against another
look the assumption regarding bitcoin as well as hopefully monero in the future is that these currencies fill a niche - so you are basically not exchanging for future appreciation but for the function it fills at that current point of time.
