Investing your $2000 in ETH, you buy all about 3.3 ETH now. Hold it and wait for ETH2.0 release on December 1, your balance can $3000 after that time.
It is actually not a good idea to invest your money right now because as you can see in the market the price of ETH already pumps and it is too risky to do that, maybe if you already invest that before the pump happens, you can already see that your money is growing but at a time like this, it is too risky. And about the ETH 2.0, we cannot predict what will happen next once it is being released. But still, we are all hoping that once it was released that it will have a big impact on the value of the ETH itself.
Despite all the good news surrounding crypto that will positively influence the price of the market and the upcoming ETH2.0 you still consider invest in ETH at the $600 price range to be risky? I will advise you make research about the purpose of ETH2.0 which was ETH own way of preparing for the mainstream and that the reason why the Australian government are planning to you ETH to create their own digital currency.
