I agree and disagree. right now all these cryptos are quite young and basic. whales problem can be addressed and hopefully WILL be addressed. if you look at number of coins right now, only handful of them gained mass popularity and are actually used for something else than speculation. XMR for darknet payments, LTC for payments in general, ETH for dapps etc etc.
still, I believe that if something goes seriously wrong in ie LTC land, people would switch to something else. I dont think we should think of national crypto currencies in this new scheme - more like popularity :)
best regards, thank you for kind words
