For me .. its a matter of investing time and effort.. it depends of what actions have you done.. must plant a seed first to harvest a fruit, in other words effort first before pay off

2 months is too short time to ethereum can reach 2000 $. At present, ethereum prices fluctuate around $ 490, I think it will take more than 2 months for the ethereum to reach $ 2000, because this is too high compared to the present. Right now, if you want to invest ethereum in the long term and make a profit, then I recommend buying, because the price will increase in a few months.)
