I have never sell bitcoin that I already have if I do not need money, I mean I just sell bitcoin according to my needs. for trading I prefer to trading altcoins because there are many altcoins that are very good for us to trade
Each bad news people thinks ok we are out of BTC and they will see it the only one holds like BTC and LTC , all bounce back to normal level as for this month more than 5k and LTC as 60$ , we used on these normal days with BTC high low .
Actually you only need to hold your Bitcoin, you still can get a lot of profits at now. Litecoin has dumped to low price again, it can not keep its value after reached @0.02 BTC in second time. But look at the price of Bitcoin, only Bitcoin is raising up more value and stable at high price every month
