With the recent rise in the price of bitcoin to us dollars to as high as $3305 as at yesterday, the best period to trade your bitcoin is now.
if by "trade" you mean sell because it is a big number in your eyes then no, it is not the best time to sell because bitcoin has just started moving up. and will continue as the BIP141 locks in SegWit and then the follow up rally will be as SegWit activates and we see it in real action. this is actually a long awaited rally.
but if you mean trading in the normal sense then there is nothing different. you could have traded bitcoin (bought and sold and bought back) the same as before and in the future!
