Yes, sell high...buy low...The experts are pretty bullish that BTC will rebound. Based on the numbers, I tend to agree, so @suf1an, be encouraged. Of course, I'm sure you have your strategy in place for a buy/sell limit.
I sense most people who bought in @16K expected it to keep booming without the 'unforeseen' glitches. I didn't follow the Elliott Waves on this round of the upsurge; but, I'm sure there were prolly warning signs that it would take a dip.
Best regards.
Peace.
