The worst part was investing in ETH, and every time I thought I could buy at the lowest price, there was another crash. I've lost a lot of money so far.
The same thing happened with me as well buddy, I invested twice in ETH thinking it will grow, but as of now, I am in huge loss. Though we don't know what might happen in future and if and only if there is a bull run, and it crosses $450-$500, I will be in some profit. Only hoping for the best will be a choice.
Another bad decision is I didn't sell off few airdrop coins, which went little high upon listing but now they are like nothing to where they were.
