Pretty likely, shakeout coming.
However, I'm not selling any because in the big picture it will go much higher. Think about those who dumped at $600-$800 on btcs way to sub $200, only never to buy them back. They felt pretty good for a year or so, now not so much.
Timing the market is way too hard. I have tried to just hold everything long. Every time I have sold any type of crypto, I have ended up regretting it a few months-a year later. If you don't need the money for living expenses, or another investment that you think you can do better on...the best thing to do is definitely just hold and ride out the highs and lows. I mean even LTC...if you managed to hold through what I think was multiple years flat in the $3s...now you are pretty happy.
