Testing is really necessary because it is very useful, but the results will certainly not always be the same at other times because DIVI is also a coin whose price can go up and down like the others.
And testing like this is very not recommended for newbies. But in fact, precisely newbies are those who are trapped with the hype of meme coins so far. 
The price will change very drastically only in a short time, and once we miss the moment, we may not get the right moment again to sell the tokens. And then, we lose our money.
That is why this is very risky.
But, if we are already very familiar with the cycle of this kind of coin on the market, we may utilize that small chance to get big profits in a short time.
