The same use case as a crypto you may have heard about called Bitcoin, but just 1000 times better

For those who did not get that one I will clarify - Currency, Fiat Killer.

To be the best or one of the best currencies in the world IS the most profitable and most world-changing use case in the world.

There is no coin in top 100 who can compete in tech with Divi. I do not see any real competition. Even Dash is in the stone age compared. Read the divi whitepaper and you will realize this. And no the old coins cant just upgrade in the same time it takes Divi to implement the roadmap. It simply does not go that fast to upgrade an old coin. They will be years behind because everything about the old coins is outdated from the core and out. Also Dash use miners who will get pissed if they suddenly went 100% PoS. Same with all PoW coins. The miners are powerful. They will do everything they can do to stop it. Hint: "miner centralization"

And no, speed is not the most important factor. Every crypto can upgrade its speed more than enough to scale long term. Also coins like EOS sell decentralization for insane speed. Even Vitalik Buterin said this. But again, every crypto will have more than enough speed within a few years. No need to sacrifice decentralization for speed.
