If you bought it during the hype, that seems to be worrying and can't really feel good. I'm not sure if holding still a good idea, as the 2017 tragic dump seems to be a hint for us to make a sell rather than keeping it in your wallet.
Buying at the peak and seeing the market movement right now is really worrying, you need to have a good insight in terms of dealing
with your decision making, it's not going to be easy as the value is now falling and the recovering part may take that long, unless you
are aiming for long term hold which you set everything up before investing.
What I mean is that is to think wisely, selling it now could be the best option (for me). In fact, we can buy it again if we want to. What makes it important is to save our funds as it was more regretable when we miss this thing just like we did last bullish season.
You can ydo this if you have that nerve to play with the volatile movement, though it's risky but if you have good faith with your knowledge
it's possible for you to work it out and earned back those losses.
