It's always hard to predict the price of the coins but all the crypto market needs a chill sooner or later .
I dont see your logic here.
Altcoins are becoming more famous than ever these days.
More and more companies, starts to accept BTC, and soon other altcoins, as altcoins gives the oppertunity to leave out the middlemen(banks, etc) for their take, AND remove the payment fees for good.
Lets take an example: We have a person doing daily/weekly/monthly transactions, both big and small (could be shopping for groceries, maybe an online casino, etc), doesnt really matter. These transactions will then go through the bank/middleman(unless he have cash). And ofc the bank/middleman wants something in return, for handleing these transactions. So they decide to take a small fee of maybe 0,2% (more or less) depending on their greed.
When people use altcoins, these fees could be avoided for good. which would be some of the top reasons to why its NOT going to take a chill soon. Id say its heading the opposite way here.. In a digitalized world as ours, alot of economic changes/adaptions are happening exponentially. Since sharing info has become so easy, and the demand for more resources and privacy is increasing every day. Using altcoins as a basic currency, would be a "normal thing" in the near future.
Basicly same pattern as when websites/cellphones/laptops was developed. They keep having an increase in demand, as they make things alot easier, and helps people to save time and money.
