I think that the first question should be .... will ever cardano deliver its product?

Its "almost ready" last 4 years. In 2017 cardano was a promise only, in 2021 cardano is still a promise only.
Crypto - place where promise is worth more than productSecond question is ... will this long awaited product be better than BSC, Solana, tron and other coins that are "cheaper and faster Ethereum"?
Third question - will devs flip from BSC, SOL, ETH to ADA and move their projects there? I doubt it because there is no infrastructure. Like eth and BSC have (dozens of wallets - metamask, bridges etc).
And finally if all above questions are answered we may ask who will deliver first dex there. Not before.
I almost never use ADA, If indeed the product hasn't been launched yet, why is the project so HYIP? What causes investor confidence to be so high that the price of ADA is also high?
