I don't mind a system like bitcoin existing but bitcoin itself has way too many problems to be useful and actually is detrimental to the environment. It takes way too long to process a transaction, it is massively energy intensive for what it is, and it's been hyped up like the Californian gold Rush.

Sure it was created to solve a problem but it doesn't actually solve that problem very effectively. It also introduces an infinite number of new problems that no other currency system has ever experienced.
