Basically, you are claiming that many people who lost their money in scams (first in shitcoins, then in ICO's) somehow helped Bitcoin rise, right? To me, that looks like a very flimsy argument. Honestly, I'd rather say that it only hurt Bitcoin image as well as its price tag. You see, it is not enough to disagree with someone's opinion. You should actually bring some facts to the table in order to support your point of view
This is only based on my observation, there's a lot of ICO in 2017 and that was the time bitcoin reached its new ATH, so that growth could be associated to altcoins whether people are scam or not, and I also believe that those who got scam will not gonna leave the market right away, they will learn and find bitcoin as a safe investment
It seems you are confusing correlation for causality
In other words, you implicitly assume that Bitcoin reached an ATH due to altcoins emerging en masse, right? Or, put differently, if it weren't for altcoins, Bitcoin wouldn't reach so high a price in 2017? If anything, I think it is quite the other way around. For example, if there hadn't been a split which led to the creation of Bitcoin Cash, Bitcoin would have reached even a higher price by the end of 2017 (and probably wouldn't have fallen so much in 2018)
The market is big, people are looking to diversify their investment and I don't see any reason why altcoins should be eliminated when they offer great idea and they are building it for us to use in the future
To tell the truth, I don't see that as a diversification as it looks and feels more like stealing people's money
Don't generalize the altcoins, true that majority of them are scams but as the market is maturing, people will realize and like I said will learn from their mistakes. We can look at the market (
https://coinmarketcap.com/) once again and we will see there are altcoins that are producing results and one of my favorite is the BNB, but at the same time I am also a believer of ETH
I hope you aren't closing your mind on altcoins because you are hating them. I'm just stating the facts based on my opinion
This is just another example showing that people don't pay particular attention to detail as I was not generalizing all altcoins (I said "Bitcoin as well as a few selected altcoins")
