Most of the time we regret buying something when we see the price drop. Then we don't have any more dollars to buy. But if we divide our total dollars into three or four parts and buy slowly at each down, then the chances of profit are high. And if we get profit after buying first, then we will sell. For this reason, I think it is better to invest little by little instead of investing all the dollars at once. What is your opinion?
Well, that's a nice strategy called as DCA which many people prefer to use. It's a proven method for getting a good entry and exit price.
Newbies should definitely try this method as it has not technical or fundamental analysis involved.
You just have to buy it at regular intervals in every dip and keep accumulating over the long term.
The same strategy can be used while selling the coins also so that we keep selling at every peak to get a better average selling price.
