I may still have some bitcoin, but I certainly hope it becomes worthless. It's turned out to be ridiculously energy-consuming, and it seems to be used mostly for speculation rather than payment. Transactions have become too slow and expensive to be efficient for a payment system.
It's entirely possible that cryptocurrencies will be the future, but it won't be bitcoin. It needs to be more efficient and more scalable than that.
Exactly. If a cryptocurrency has some stable basis that's more efficient than proof-of-work (== wasting energy for its own sake), and has cheaper, faster, more efficient transactions so it can actually be used for small purchases, then I totally think that currency could conquer the world. Bitcoin itself is just too limited. Great idea, but too many problems.
Has there been some revolution in bitcoin tech since Dec 2017? Is it not based on wasting as much energy as possible anymore? Is it suddenly being used for far more transactions than before?
