Actually the presence of crypto is also full of business competition.
Rarely correct. Its much more competitive when it comes to the IPO and stock markets. Here you just see a bunch of whackjobs trying to get rich. Coinmarketcap is an aggregator of coins not a court to decide which one is better than the other.
If they are not able to compete well, of course, they lose the sale value.
They lost value when they were unable to prepare proper marketing and development. These things dont come cheap and most projects are scraping for finances anyway so they go for the cheaper routes ending with inability to complete their promises of the project.
It means zero trading volume. Now it has reached 3000+ cryptocurrencies in circulation. But among them, the active ones have platforms that can be used by the public. Such as platform exchanges, wallets, mining, and platforms that provide smart contract services. So what is the fate of tokens that are only present without offering public services? Of course, they will die on the way.
True, this is why majority of altcoin projects have been nothing but snowballing and trying to keep a veil. They are worthless and one should not waste their precious bitcoins on buying them. Rather buy more bitcoin since the price is low and stock them selling in future.
