HOLDING is a good thing, but when you hold too much you will start loosing. I have learned this the hard way. I held some coins for too long because of greed and I ended up loosing.
There are some time you need to sell and buy back to maximize your profits. While there are some times you have to sell and move on.
holding is indeed a good thing, but we also have to consider it, taking too long holding will make you lose the opportunity to make a
profit, in investment you can't just wait and hold, you have to sell when you make a profit and buy again to start a new investment
