I have the same experience this time I have 5 eths but I can not utilise it. another I my balance was cur token 500 when the price went $5 per cur token I have stock maybe price will increase after that, price dumped and it was my worst experience.
What some people often forget is the sudden wasting of coins, so often we expect more gains even though dumps can also occur at an unnoticed time, this is why early take profit is always better in the crypto space.
