This thread was started 2 years ago, so we've now had 2 of those 5 years to 2022. The price now is lower than it was 2 years ago, which is not something I would have predicted. However ETH is still a very strong coin, and I expect it to be a big success as we move slowly towards the mainstream. I would guess somewhere between 1,000 and 10,000 for ETH in 3 years.
