Yes I had this feeling since the great Bitcoin crash of 2018. Not just one coin only. but a lot of them. Like I have a feeling of "I wish I could have taken profit before it goes down", or "I wish I could have hold that now than selling it early". The market is unpredictable and we just simply don't know when will it go up or down. That's the reality, and we just have to accept and move forward.
2018 been a testing year whether we will continue to have crypto or not. The market crash and most of the ICO projects that are created and succeed in 2017 didn’t able to recover those projects who are only in top chart was able to catch up. But then comes many influencers and institutional companies who engaged and make hype in crypto. We can’t really tell what can happen in crypto as it’s tok volatile and can easily affected by hype. I almost sold all my holdings last 2018 due to long dump but still didn’t give up and just try to trade more when the market recovers. We just need to believe in our capabilities to understand the marekt.
