I think the answer is simple. There is a boom on cryptocurrencies and everybody want to take their own piece of pie.
Of course after some time, most of cryptocurrencies will disapear, but ones that left will be really "strong" and expensive

Hi All,
Please help me understand in plain English how will we benefit from so many currencies?
I see so many startups with decentralized blockchain ideas with their own crypto currency.
Today I purchased oatmeal directly from a mill at their website.
This mill sells its products thru grocers and other online stores as well.
They probably gave 3% to the credit card company, which they could reduce by using blockchain.
But if every store and every business starts creating their own currency, then I will have to go thru an exchange to convert BTC or ETH to that coin to make some purchase.
Then we would need miners to process all those transactions in various coins.
Why can't they just use ETH? Just like all IPOs use dollars.
Thanks in advance
why do you expect something to be left at all, maybe there will be an eternal period with volatile unreliable currencies. like it was in the past, throughout whole human history
just think about the big currencies that dissappeared: deutsche reichsmark, all those royal currencies, of various dynasties. etc. these people of course took controll over the banks later, but nevermind.
those that work for money they suffer when there is a financial syndicate controlling everything with their agenda, like its the case in many countries in the developed world as well, i am not even going to discuss the developing countries.
