We know that the primary purpose why we even have anything like altcoin is because of Bitcoin and this has been fully reflected in the fact that when there is a major event that affects Bitcoin either positively or negatively, all altcoins and a bunch of meme coins feel the effect directly.
We also know that what makes Bitcoin relevant is firstly due to it decentralized nature and it ability to making international transaction easier through the p2p concept and that Bitcoin has taken away the issues of unnecessary middle men and bunch of controls and regulations that's common with fiat or international banking systems and that the whole crypto ecosystem revolves around Bitcoin and that whatever project that has ever come up after Bitcoin have all been centered around modeling on the functionality of Bitcoin and maybe focused more on the volatility aspect of Bitcoin to attract individuals and investors to those crypto project while bitcoin in itself has all those qualities of volatility and provisions of the solution to international transactions that these altcoins hope to solve.
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?
It's true that altcoins feel the direct impact if BTC experiences a DIP or a rise in price and value, an also like you said altcoins can be a distraction to Bitcoin, and it might not also be a distraction,
Let's have a case study, an investor who wants to Invest in other digital assets outside Bitcoin will have his resource for investing divided between Bitcoin and other altcoins, in this case altcoins becomes a distraction, because the resources that would have been used to acquire only Bitcoin has been shared between Bitcoin and altcoins, but an investor who believes only in investing in only Bitcoin no matter how high the price and values of altcoins, will not see altcoins as a distraction, so it depends on the kind of investor you are, for me
