I recently discovered, few weeks after the ICO the value of coins/tokens normally drop by a minimum of 30% - so that is my entry level again.
Meaning once I noticed that, I'll just go ahead and rebuy the same coins/tokens at cheaper rates. By doing that, I can make lots of profits.
Tactics are good but it's only temporary. Over time and the fluctuations are unevenly spread. holding is always the easiest and simplest way to increase revenue from bitcoin and crypto. You will regret it if from this point, selling pennies can be a mistake. Good signs are coming back more regularly today.
