You keep the same amount of ETH, just the value is lower. It's just like any share etc
The markets are 24 * 7 so expect constant change.
you have 20$
suppose you bought 1 eth with 20$
and next day eth price goest down to 2$
so in usd, you lost 18$ if you withdrawal... if not, then you still have 1 eth which you purchase,
so just HODL and when price goes back to 40$ you can withdrawal and gain 20$ profit from it![]()
