I think you are absolutely right. But today we are developing a trend of speculation rather than a trend of innovation and discovery. We see a lot of underrated coins. This is very sad. For example, XRP is used in the banking sector and is very important for society, but it coin have very little price and people do not pay enough attention to it.
I agree that the price of altcoin on the market tends to be speculation. But if altcoin we hold has a product and has a solid developer team, I think it doesn't matter if the price is currently down. Adoption is indeed important so that investors trust on the project because for companies, to get money there must be products that are sold
