Again, Most of those who have had bad experiences in the crypto ecosystem are individuals who invested in some altcoins thinking it has the same potential as Bitcoin and the fact that it's always a norm in society to call Bitcoin one of the cryptocurrencies, it's no strange that altcoin might have played a great role in reducing the level of adoption of Bitcoin globally.
This begs the question, what if we had only Bitcoin? Wouldn't the level of adoption outgrow what it currently is at the moment?
Do you think that altcoin is a major distraction to bitcoins adoption?
I don't think altcoins have reduced the level of adoption for bitcoin in any way, but as a distraction it has been a very good one that has swayed many into believing and even thinking that most crypto currency are scam and not good to invest in, and I would even say that its not worth it to invest in any other crypto currency other than bitcoin if you really want to invest and not gamble away with your funds.
Going back to the topic of discussion, I believe that altcoins are also playing a role in bring adoption to bitcoin, cause right now many that started put with some altcoins are now seeing clearly the need to participate in investing in bitcoin, the margin of superiority of bitcoin with other altcoins is now clearly seen. Some persons started out their investment or tried out crypto currency due to the hype of profit from one altcoin or the other, and even if it didn't turn out well, they now have an idea of what crypto currency is all about.
Personal is started out my crypto journey from one altcoin which was tera luna, although it didn't turn our well for me, right now I'm investing in bitcoin cause I see light in it and this is same experience for many others too.
In conclusion altcoin has played a role in both contributing in mass adoption for bitcoin as the real deal of the crypto space and also a distraction for those seeking quick profits in the crypto space. I believe its balanced.
