Ethereum was far ahead with smart contracts and Dapps in the past.Now,ETH is far ahead with defi and yet it's still not the number 1 cryptocurrency in the world.There's might be something wrong with ethereum. 
Its not slow and have plenty of development. And this is wrong for the hodl cult. You dont proper hodl if you can move the coins around.
None of the cryptocurrencies are really decentralized, even bitcoin. If you have 1% of the users holding 99% of the supply, then its not decentralized. And if you have whales manipulating the market, to accumulate even more, then you have increased centralization of supply. You can say the tech is decentralized, but if the supply is not, people will not use the tech.
The exchanges are to blame for it, as they allow the centralization of supply. A exchange with only 5btc in the last 24 hours dont have any issue when 100btc enter in just one account and burn the entire book. Its good for them, as they will get more money from fees, but this hurts the project, as a lot of people will have their money stolen, and many of them will not come back to bitcoin after the crash.
