Longing Bitcoins is always a good decision! Yes, it would be better to buy the dip, but it's not always possible, and too much waiting can be a wrong decision! Will it be I will see, because I am waiting the price to drop more to buy more, in case I made a mistake I will have to buy at higher prices, and that's a loss!
I am not trading anything special, but I am selling some of my holdings, and I am creating buy orders at lower prices... like it's what I do all the time... these times are more exciting because the prices are much higher, but except that it's the same thing!
