Now, trying to relate the above to BTC.
Is BTC at the introduction stage? I asked because there are still campaigns promoting BTC and BTC is not yet generally accepted by all.
where did you saw the campaign ? i dont see btc being promoted but it was the product/service that is being advertised and if you saw a btc logo in it , that means btc is supported . btc is not new to be in the introduction stage but thousand and millions of people in the world already recognized btc.
Is BTC in growth stage? I asked because in past few years we have experienced improved sales of BTC.
yes it can be . the price of btc continues to grow except if there was a bear because the price growth was paused during these times .
Is BTC in maturity stage? I asked because after the recent dip in BTC it seems it's sales has reduced and there are altcoins too that are competing with BTC.
But I am very sure BTC is not in Decline Stage.
maturity stage is where btc fits the most but maturity stage does not define a decline but it defines a growth aswell . recently btc is going in a decline stage but that seem to be over now
