Why you didn't buy when eth was around $100? And now that it's increasing you're thinking to buy some and don't you think you're being FOMO?
I don't want to speculate the price as so nothing is certain but if you think this will be a good entry for you then go.
It is basic instinct of investors.
I meant, investors tend to wait for deeper price even when the price drops deeply and hit bottoms, they often hesitate to invest immediately, and expect cheaper price.
Then, they are wrong certainly.
After that, when price rises, they expect, expect it falls again.
Then, a long period later, when price rockets to peaks, they lose patience and decide buying immediatly
Very well done investments, in most cases.
