Cryptocurrencies will win because we are Hydra

I love you Steemit and Blockchain
We are like Hydra:

Only Crypto Currencies that are not dependent on mining will have a future.
Mining is pollution!
At Bitcoin, i'm sure that he gets easely problems withe the mining - it can be fast banned by simply pulling the plug of the mining farms.
Bitcoin has also only 21,000,000 coins and how should the mining farms be paid off, if the last Coin is finish?
The last one will bitten by the dogs!?
Bitcoin will let everything implode unless if we doesn't separate it from our mind that we need bitcoin.
We dosn't need bitcoin!!!
The technology is the profit and not this coin without a long therm future.
Blockchain will improve the world and destroy corruption.
The revolution begins with us!!!
