Yesterday I sold my Bitcoins of 1.21 not at the highest thinking it would go down so I could do a rebuy , seeing a downward trend (-$200), but instead when waking up they were higher for about $200.
I initially bought them for $5500. Now I don't know what to do. If i need to rebuy the same amount it wil cost me about 450 dollars more then when I sold them, thus losing profit.
When SegWitx2 got cancelled and Bitcoin Cash skyrocketed I also forgot to sell and Hodl until I lost all my profit.
Well firstly you bought them at 5500 so I'd imagine you're still in profit, do not let this influence your decision but perhaps let it ease your stress. You must now consider what will happen with the price in the coming days and forget about your previous trades. Really given it seems you would look to rebuy the question is then just of if you should buy now or wait for a lower price. Personally I think anywhere around the low 7000s is about as low as we will go again before another run up to and beyond 8k.
