I still don't understand XRP. All nodes are controlled by ripple labs. Ripple labs can change the protocol when ever they want. They could block transactions, create new XRP, or even steal directly from your wallet. With this setup why does ripple even bother making it a blockchain? it could be easier and faster to have a centralized database with address and XRP value entries. The whole point of a blockchain is to have a consensus mechanism for a decentralized network but XRP is centralized. Ripple controls consensus.
With altcoins, it is all about the hype.
There are meme coins entering top 100 based on market cap in few days. Just a meme coin with no use made for fun. It is obvious what the end fate of such coins will be. Those who invest in these coins at last will suffer very badly. The blow will be so hard that they might not be able to recover entire life.
