It seems to be true. However, there is still a small risk that it can be down (for some time only, to get up after). The closer we are to Ethereum 2.0, the more people are ready to invest in ETH, and altcoin is getting stronger, which is also good for the price of it. WE should remember that its lowest price was 0.68 USD (August 2015), but then, the Moonrise started. We will see it again.
