Not aware of these storage-related altcoins but in a quick view, are they really a big deal? Dropbox, Google Drive, Mega, Asus are already dominating the cloud-storage. What's the advantage and benefits that these coins will bring in terms of cloud storage?
I will follow this thread for more references.
First I also had same impression as you did however if we think a bit more then we are in crypto which means these projects might be rewarding their users in terms of tokenised payment, by spending these tokens fir their services and products. Mostly these are the kinds of ways where we spend them and use it. That’s why it’s preferred over Google, Amazon etc. Plus you get sort of anonymous structure to which may not be 100% anonymous but could be one step more than Google at least. 😂
I see no difference in storage coins or coin which are used for Exchangers. I mean we have share market then why use crypto exchanges? So there you go same story for the storage coins or any other utility project out there.
