It is a matter of time for ETH to reach $800.00 again. I do not know if it can climb to $1000 in Jan but it will def do it till Feb.
It stands around $750.00 at the moment, so i guess it is a good time to buy
https://www.tokens24.com/coin/ethereum/In any situation if you can wait then invest in Ethereum as long term investment. You would get stable income and will not worry about price fluctuations. ETH is good currency. I have a lot of these coins.
ETH already provides 3 times more daily transactions than Bitcoin. And this gap will increase for multiple reasons. It is very likely that ETH will tenfold very soon.
