There are too many projects that we don't really need it on blockchain.
Sometimes, I think there is a black swan (Blockchain is useless in real life) lurking around.
Yes, most of these projects are uncalled for and those who are running those projects are just doing it to make their money and thats it. I see all these projects, but I still wake up and see that another person copied the same project, quite funny. And they be expecting people to invest in projects that are not unique. I dont even have time for all that, only making use of Bitcoin whenever I want to make transaction or maybe if I want to invest for a while or trade.
Blockchain technology if fully deployed is absolutely a way out in term of curbing election rigging, Russia had already adopted it for voting process also its very useful in chain supplies, medicine and other valuable sectors of the economy the OP is laying more emphasis on the usefulness of this technology on mainly cryptocurrencies not mindful of the fact that this technology goes beyond using it to create shitcoins.
The truth is that I have seen a lot of claims on what the blockchain can be used for, but none of them are being fulfilled at all. I have seen and heard a lot of things, but this one of election is what Im just seeing today. I dont know how that works or how exactly Blockchain is going to help to curb election rigging. The way it is built, that seems impossible to me, but I will do some research though.
