That isn't really a drawback for the investors. High transaction fees doesn't affects them. Investors focus on returns and volatility of any coin. Investors still invest in bitcoin. Its the investors who have taken it to 19K despite of such high fees and time. Now what we are seeing is just a correction and nothing else.
I see from your footer that you are into gambling so lets cut the crap about investing and call it by it's real name "Gambling"
The miners took a gamble when BTC was shooting up that they could increase the fees because they have become a monopoly
or maybe you would like to explain why we need 20,000 full nodes just to perform 7 transactions per second
This correction is what you get when you have a nice car and the roads or network don't work, you sell your car so fix the
roads (fees) or the price will go down because people are jumping out all over the place.
"Let the trend be your friend" is a term you would have come across had you worked in finance
