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?
It doesn't guarantee you more profits either, Instead you can create multiple orders with different price that you wish to buy so the trade will be executed automatically when the price hits, and it;s not new since most of the bots fills the trade history with all the prices so chances of getting it is alsm slim unless there's enough liquidity to actually buy at that price.
If you want to maximize your profits, buy when the market dumps hard and just wait for the green days to be back which is nothing but buy low and sell high.
