I agree that the market will be a very long time to recover, but do not want to as much as 2 years! Perhaps in 2019 will be the beginning of the rise up!
This option is not excluded. Imagine what will happen if the SEC rejects the ETF in 2019. It will be a new fall, which may take a long time
In the end of 2017, the growth of the crypto-currency was without ETF, why does everyone think that ETF should become the driver of growth this year? More significant event in this regard, it seems to me, is halving in 2019.
