2017 was a big year for ethereum and majority of the ERC-20 tokens. Further there is no big growth, the market kept crashing. None expected such a huge loss in ethereum value falling low to $100 from a value close to $1500. By those days bitcoin too experienced a great fall in its value. Later when bitcoin started to pump high ethereum was the same without big growth. Hope 2020 will be big for ethereum.
Yes, everyone who was here remember 2017, my opinion is that correction for 2 years, with a little recovery - these are only the first, maybe not quick steps to new records in the value of all coins
