You had a golden chance to invest in 1800$ and get instant 1000$ rise in the a week back, now also it went 2500 and now back 2800$. So my suggestion is if it goes down take it cause post Aug 1st there is a bigger rally coming, take a part buy at every dip, currently it's bit high so wait and watch. You could yet go in but I feel it's way to high now, but then there a risk it could just shoot up again. Take a gut call based on your financial needs.
