Since Bitcoin blockchain has one of the highest fees in compared to other blockchain, then in times of very high fees, then shitcoin investor will be forced to hold their coin till whenever the fees goes back to normal. What if the coin is dropping down. Am just saying that an investor will choose to invest huge amount into those shitcoins instead of directly investing in Bitcoin. I see no point in doing that though. However, its their choice to make.
However, the habit of chosen centralized exchanges for storage of our Bitcoin during the time of high fees is highly condemned and should never be seen as option.
So in essence what you are saying is that irrespective of the prevailing high withdrawal fee at that time, people should always withdraw their bitcoin off Cex? Well to me it depends on the quality of the holding that the investors are holding in the Cex at that time. If the withdrawal fee is as high as 20% to 30% of the bitcoin deposit you have in the Cex, don't you think it will be better to leave it there for a bit and allow the bitcoin withdrawal fee come down a little? Let's assume you have like $400 worth of bitcoin in Cex and you are paying up to $100 -$150 in withdrawal fee. It doesn't make sense that way. So at this point I think it will best if you allow the withdrawal fee to reduce before withdrawing. But for investors who don't care about the fees they are to pay they can go ahead and withdraw. But for small investors that are still starting and doesn't have much money they can hold on a little longer for fees to reduce.
