Absolutely agree with you @op, using both short and long term strategy in building our portfolio is the best way, i have also observe this scenario with some of the asset i own and i found out that this method is best way to accumulate even more, some of my tokens increases by 10% but i didn't take a short term profit by selling and buying back at below, i actual regret not doing so because now the price is down, i should have been able to make a decent short term profit if i had done that, this is why @op idea is good.
You need to assess each time you take your position, setting up your strategy according to how you percepts the market is really important. There's always potentials if you have good knowledge with the patterns that you'll going to use.
Investment strategy always differ from each traders points of views, some are good riding with the daily market and other are focusing with both long term and initial offering investments.
It's all about how you see your advantages in picking which strategy to follow, being adoptive to anything will bring you more opportunities.
