The price of crypto is unpredictable even the timing of Ethereum crossing $500 may not be realistic this year. I don't see eth crossing $500 by the end of this year. Prices was experience corrections 3days ego, as eth was selling for $380 region but it unfortunately went down to $343 today( 21/09/2020).
Infact, the timing or prediction of crypto market is difficult, obviously anything can happen.
