That's what I am planning right now man, already made my decision recently I've sold my part and the target you suggested is great. Maybe I've find some additional resources next week as my savings will be used to buy back once price starts to go down.
It is good if you already sold some parts, and that will be best if you bought XRP at $0.2 and sell it at $0.6 because you are making a nice profit. You can wait for another time to buy back XRP, especially if the price can go down below $0.5. But to see $1 again, I do not think that will be easy and it will need more time to reach that price. It can increase to $1 if the investor wants to back to the project, so XRP can have more support to lift the price. But lets we wait and see if that can happen later.
