Bitcoin-Amazing Idea but with great bugs.

We all know what is bitcoin. It runs on a blockchain technology which is ground breaking. what i do want to point out is other than just a good way of transferring money it has no value. In-fact, it is bad for the environment. It uses so much electricity to solve a pointless puzzle to do really nothing. Mining is an illusion. There is no such thing as bitcoin mining. We are just wasting a certain amount of energy so that we can solve a stupid puzzle so that we can reward miners for wasting electricity. Thats all there is to mining. In other words, we tell a few people : Hey, why dont you burn some of your electricty and I will give you a bitcoin in return. Worthless. Don't get me wrong blockchain is great but bitcoin as of now need to stop wasting electricity and find a better way of solving double spending problem. Mining is just detrimental to our prosperity.
