I did the opposite,haha. Instead of buying, I hurriedly sold my  BTC.70 when I see it falling on the $3k value. It was a tough decision to make. I am not an expert trader and I don't have that much money to buy because I already bought some on the $4k mark but like what happened , it still manage to fall below that. Those bastards are lucky for having many experiences in this trading because I'm sure they are always buying on the bottom.
