One of my friends bought BTC when it reached $13.5k (yes, he FOMO'd in at very high rate).
After that, BTC crossed $13950 and almost reached $14k (though it didn't touch there) and that was his target but missed by some bucks.
And here comes the dump which shot down BTC to $9800 (yesterday) and he just lost his patience and sold off everything (what a chaotic loss of more than 30%) and it was actually predicted -

Now, he's regretting for his wrong decisions. I'd suggest you to think at least 10 times before investing because if you don't have the appetite to hold on during your losses, trust me you don't deserve a f**k in profits. Patience is the key and it pays off, it is actually paying off those who bought during 2017-18 highs but held their investments without touching it.
You made me laugh my ass out, you narrated this as if I had told you exactly what happened to me too, I placed a buy order at exactly $13800 and my target was to take profit around $15k, but to my greatest surprise, the retracement happen too suddenly, but I never worried, because I know we will be back there, and probably this is what makes me different from your friend, and it is sad that he already lost.
Anyway, I dint think it is still too late, he can still buy whatever amount left from what he sold, but will have to wait for the value to reach close to $18 before he can regain that complete $13500 back. It is not so easy bro not to panic sometimes, knowing that we have whales in the market, but sometimes, we just have to give little chance to hope.
