Conclusion: Don't assume to scale through the high cost of transaction fees and get your funds get risked on the centralized exchange platforms.
It is true that some people tend to put themselves more at risk by trying to avoid inevitable situations. Short-term investments are risky and the high transaction fees are one of its consequences.
But if they are so keen about buying and selling in a small periods of time then why not? It is still their decision in the end. I do hope however that scalability issues get resolved. I know it will be long before it actually does get resolved so for the upcoming bull run we are stuck with expensive transaction fees.
