There are several strategies to this, you can't just buy low because a project dipped in price.
You need to do more researches and also understand the trade charts.
Engaging in more researches equalling helps.
How funny that sound! Serious how many traders, investors do more research when there is a dip in the market? Tell me, will you do more research when eth price dip, or bnb, bch, ltc btc, link, dash.... nobody actually have time to do any research again before buying, this are very easy to say, people hardly ever put them into practice,
In fact, it is because we are still partly on bear market, during the time of bull run, will you do research before jumping into any available dip, the price is not waiting for you, once you miss that opportunity it is gone, I miss opportunity to rebuy bch at $167 and now am hoping it will come back, just hope.
