Do not rush to sell your BTS too quickly, even though you have a profit. 2500 is still cheap. 3600 is still cheap. These levels should provide resistance for a bit, but they will be broken in time. If you manage to sell and buy back lower thats great, but dont try to do it with all your BTS, or you will get left behind at some point!
In a wave 3 bull move, the important thing is to ride the trend, because it will just keep going. There is always volatility along the way, but during this move your main goal should be to not get bucked off the ride by chasing small retracements! The money is made by staying long here.
