Now that bitcoin has reached $1000 it will be a good idea for people to hold on to their btc to maintain the price
or we can just buy more btc to push price even higher
holding bitcoin even at this stage is a good idea. i did not sold my bitcoin when the price cross 1150 in previous day and still not going to sell my bitcoin even if the price of bitcoin will cross 1200 USD level. because i am still pretty confident that this time the price of bitcoin is going to cross every 1600 use level very soon, so i am not going to sell my bitcoin in next moth or two.
Nothing wrong with that strategy it seems you are waiting for bitcoin to grow big before you sell, but if you had sold at the top and then bought again at 850 you could have made some nice profits and could be looking at even bigger profits right now.
Price is moving in a upward direction and it is predicted that price will be even higher in next couple of months so in that case its good to hold coins but if you bought bitcoins at lower price in the past then it would be smart to sell some of them to accumulate good profits and rest keep for the future hoping that price will be even higher by then.
I think it is always a good idea, that if you can sell for a profit, you sell part of your holding in bitcoin to materialize your profits, because if you keep holding bitcoin when there is a price increase then you could say you got profits but they are not going to materialize until you sell.
