It's too late in my opinion. It has already been changed over 30% within the week if I'm correct and having an entry is way more risky as at any point it may get dumped. BTC on rise too and if BTC falls, alts will follow too. I think we should wait more for an entry to ETH.
It will never be too late. We dont know if the bottom price would be on the level of $400. Were not sure if the hike could be faster than expected. The entry price is important but if you do have confidence and knowledge that it could be around 700 to 800 at a later time. Still you can earn profit without buying at a very cheap price. I think this is simple logic.
Ethereum has a lot of chance to be doubled from the current price and the launch of testnet is still on the way, in fact so many people have already entered into the ethereum staking network and that will be a good reason to buy more and more coins.
Now the price of Ethereum is in a rising phase and a lot of investors hold. I think if the market can continue to stay stable in the next few months, the possibility of ETH price reaching $800 is very high and I believe that it is entirely possible. However, we should wait for the news of Ethereum 2.0 to appear as it will be the best news for this coin and may return to the old ATH someday.
