I dont think that now its a good idea to invest in Ethereum, since everything is falling and Bitcoin cannot get a stable price, constant races up and down. There is no doubt that the price of ethereum will grow, but I think it is worth waiting to buy a coin at the level of 150-180 dollars.
The coming update with ETH is great but we cant tell the future price of ETH, yes theres a chance for a more dip price buy I hope its not going to happen because ETH is a good coin and the bull market should bring ETH to top. We can buy now or buy more later, its your choice now.
